Buying a new Computer/Laptop - Avoid screen tearing (and some more)

tbtb

Hi!

I went from Windows to Linux about 4 years ago, and from the beginning the problem with screen tearing has always been there. More or less. Sometimes it works fine for a long time, then it comes back again. Getting tired of this. really tired. So tired that I'm actually thinking about going back to Windows because of it. But I really don't want to. Linux is so much better when it comes to everything else.

First, I could only use Linux Mint Cinnamon to avoid screen tearing, then that stopped working, and I got tearing. Switched to Debian with Gnome, and had no tearing for a long time, updated and, tearing all over again. Switched around like this for 4 years now. And right now, KDE Neon is the only distro that doesn't give me tearing, until now. It's not too bad, but it hurts my eyes when scrolling in Skype, scrolling in web browser, file manager etc. But I don't get tearing when watching videos (VLC/SMPlayer/YouTube works fine). I've tried every setting in the compositor, full screen repaint is what works best, but i'm not satisfied.

What kind of graphics card works best with Linux to avoid tearing? What kind of screen? What kind of CPU? Should I go for Nvidia and Intel instead of AMD and Radeon? Please help me out with this! If you have a laptop or stationary PC, running Linux, with NO TEARING, please help me out!

Now, my computer has started to randomly freeze, randomly reboot, randomly shutdown. And I've tried everything trying to find the problem, everything except getting a new motherboard and CPU. I've tested my RAM, and it's all OK. Switched power supply, switch hard drives, switched s-ata ports and so on. I've been building my own computers since I was 13-14 years old, now I'm 32 and have always been able to find out what's wrong with my computers, but not this time.

Now I'm thinking about buying a new one. Maybe a laptop or build my own PC again. And before buying the parts or a new laptop, I want to make SURE I don't go buy components that's not compatible with Linux, or that gives me screen tearing. I don't have that much money to spend on it, around 400USD, maybe 450USD. I don't play games or anything like that. I mostly use it to watch movies, youtube, surfing, skype etc.

Is there ANY PC's/Laptops you can buy, that's made for Linux? It's been a long time since I bought new components or a new computer, so I'm not really up to speed with the latest equipment.

This is what I use today:

CPU: AMD A4-7300 APU with Radeon HD Graphics 3800.00 MHz
SSD: INTENSO SSD 128GB
Motherboard: Gigabyte F2A78M-D3H (F3)
RAM: 2x Crucial Ballistix Sport 2GB
Power Model: LC420H-12 MAX420 ATX Switching Power Supply
And 2x Internal WD 4TB HDD's.
Screen: Samsung T24C300 24" LED Screen/TV (with DVB-T) HDMI from Motherboard (built-in ATI Radeon Graphics) to HDMI-port on screen.

NOW, I'm envious :)

G'day @tbtb and welcome to linux.org :D

What a tragic story, no wonder you are peed off.

Can you give us the output for

Code:
inxi -Fxz
... the "z" will filter out your MAC addresses, better than "s".

You may already be aware we have some other commands for getting details on the graphics, so the more the merrier.

BTW - have you got vsync enabled? And have you tried Wayland over the X Server?

Oh, my wrong, got 2x3TB WD HDD's, not 4TB. And I just added 4GB of RAM. So, total of 8GB RAM right now.

I have vsync enabled, "full screen repaint", tried all the options for vsync available in KDE Neon, full screen repaint works best.

Have tried wayland, but Plasma (KDE) just crashes and get's really...unstable when I try using it. Right now, I just want to throw this machine out the window, and smash it to pieces. Yes, that's how I feel.

Most annoying problem right now, is the random freezing, random reboots and shutdowns. Sometimes it runs for days without any problem.

Merry Christmas btw :)

OK, Ta (pron. "tar", Aussie for thank you) for that output, Mate.

(Wizard appears in a puff of smoke humming " 'tis the season to be jolly")

If you haven't made the acquaintance yet of Tony George's Timeshift, now is a good time.

Read my Tute here and apply the PPA to your KDE Neon, and install it.

I'll be back shortly.

BTW - also a good easy tute by Linux Lite here if you prefer.

Did I say don't throw that machine out the window?

If not

DON'T THROW THAT MACHINE OUT THE WINDOW ... YET !!

Got some leads you can try if you are interested, putting them together, back soon.

Just so you follow my methodology:

Screen: Samsung T24C300 24" LED Screen/TV (with DVB-T) HDMI from Motherboard (built-in ATI Radeon Graphics) to HDMI-port on screen.
... got me to Googling

linux tearing faulty hdmi cable

... went to the Tom's Hardware link http://www.tomshardware.com/answers/id-2364689/bad-hdmi-cable-screen-tearing.html

and had a read through that. So I guess that is an obvious question for you if you have not tried a different cable?

Also saw the references on vsync from that search, hence my asking you.

One thing led to another, and thus the Wayland query.

This reference is worth reading, for a reasons I will explain - https://unix.stackexchange.com/questions/182801/why-is-video-tearing-such-a-problem-in-linux

The second answer, there, posted by their member kirill-a and receiving 16 up votes, was edited by one Stéphane Chazelas . This is a significant name in Linux.

Linux's main terminal shell, the Bash (Bourne Again SHell) is maintained by one Chet Ramey.

Around September 26 2014, we had our most significant flaw found in the Linux Kernel, and the event was known alternatively as Shell Shock and The Bash Bug.

Stephane was the one who found it, and he reported it to Chet Ramey that day, and the entire Linux Community, led by Red Hat, had it wrapped up within 24 - 48 hours. New kernel, &c.

So I figure if Stephane has edited that Post, it is likely good value. (You've gotta think like a wizard - weird).

To cut a long story short, (hurrah, they cheer, Wizard turns some into toads and breaks out his 9-iron)

I found this video, it is 6:35 long. The guy talks more than he does, or shows (don't know anybody like that), but he references a PPA (Personal Package Archive) that can be added to a Debian-derivative Linux, which should include your KDE Neon.

He also deals with the issue at his blog, here - https://ajreissig.com/eliminate-screen-tearing-amd-graphics/

DO NOTE his reference to some having problems, and hence I reiterate you should make the acquaintance of Timeshift, so that you can roll back your system if need be.

I'll leave you with the video and let us know how you go.




Cheers

The HDMI cable doesnt look like the problem - if so the tearing would not stop rendering videos.

It looks for me more likely that theres a driver problem as there is also something marked "unloaded":

"Graphics: Card: Advanced Micro Devices [AMD/ATI] Richland [Radeon HD 8470D] bus-ID: 00:01.0
Display Server: x11 (X.Org 1.19.6 ) drivers: ati,radeon (unloaded: modesetting,fbdev,vesa)
Resolution: [email protected]
OpenGL: renderer: AMD ARUBA (DRM 2.50.0 / 4.15.0-43-generic, LLVM 6.0.0)
version: 4.3 Mesa 18.0.5 Direct Render: Yes"


On the otherhand the Mesa Driver seems ok - thats afaik the 3D-Part (OpenGL, Vulcan, whatsoever...) of the driver. As most video player make use of hardware acceleration that would also explain why video rendering doesnt cause tearing while the classical desktop rendering does.

Can you run "lsmod" and print the result? If the module is obvious "modinfo <module_name>" would even help more.

err... and as I notice just jet, am I right that there is the Radeon HD 8470D and the (IGP) A4-7300 APU with Radeon HD Graphics? Can you then check if the monitor is plugged into the motherboard or into the graphic card?

Perhaps something like

Code:
lsmod | grep video
... might shorten that search?

BTW @mal-2 welcome to linux.org :)

Not sure if that works. Lsmod shows only a single string per module. At my Intel driven laptop it's just "i915". So it could also be something like "HD8470D" and for the APU I have no idea at all. I looked also around on the web and found often mentionned "frgxl" as driver name in combination with the APU.

Unfortunately I didnt pay close attention to AMD drivers over the last years but if I'm not wrong there was a change from closed to open source (and possibly that came along with a name change). So I have really no idea.

But the modinfo gives some more information in the description:

filename: /lib/modules/4.******-amd64/kernel/drivers/gpu/drm/i915/i915.ko
license: GPL and additional rights
description: Intel Graphics
author: Intel Corporation
author: Tungsten Graphics, Inc.
firmware: i915/bxt_dmc_ver1_07.bin

So he could try this little script which shows the lsmod-string with a short modinfo description.
Code:
cat /proc/modules | awk '{print $1}' | while read line; do \
echo  "$line \n=============";\
modinfo -d $line;\
echo  "\n\n";\
 done | less

Sometimes I just love the "Tab" with Bash-completion. Just hit it some moments ago and found a program called "xdriinfo". And guess what that program does? It displays just the connected screens and the graphic driver :D

If not available, X11-utils will provide it.

Just Enter "xdriinfo" and it prints out the screen and the driver.
With "xdriinfo options <driver_name>" it will also list the driver config.

Just so you follow my methodology:



... got me to Googling

linux tearing faulty hdmi cable

... went to the Tom's Hardware link http://www.tomshardware.com/answers/id-2364689/bad-hdmi-cable-screen-tearing.html

and had a read through that. So I guess that is an obvious question for you if you have not tried a different cable?

Also saw the references on vsync from that search, hence my asking you.

One thing led to another, and thus the Wayland query.

This reference is worth reading, for a reasons I will explain - https://unix.stackexchange.com/questions/182801/why-is-video-tearing-such-a-problem-in-linux

The second answer, there, posted by their member kirill-a and receiving 16 up votes, was edited by one Stéphane Chazelas . This is a significant name in Linux.

Linux's main terminal shell, the Bash (Bourne Again SHell) is maintained by one Chet Ramey.

Around September 26 2014, we had our most significant flaw found in the Linux Kernel, and the event was known alternatively as Shell Shock and The Bash Bug.

Stephane was the one who found it, and he reported it to Chet Ramey that day, and the entire Linux Community, led by Red Hat, had it wrapped up within 24 - 48 hours. New kernel, &c.

So I figure if Stephane has edited that Post, it is likely good value. (You've gotta think like a wizard - weird).

To cut a long story short, (hurrah, they cheer, Wizard turns some into toads and breaks out his 9-iron)

I found this video, it is 6:35 long. The guy talks more than he does, or shows (don't know anybody like that), but he references a PPA (Personal Package Archive) that can be added to a Debian-derivative Linux, which should include your KDE Neon.

He also deals with the issue at his blog, here - https://ajreissig.com/eliminate-screen-tearing-amd-graphics/

DO NOTE his reference to some having problems, and hence I reiterate you should make the acquaintance of Timeshift, so that you can roll back your system if need be.

I'll leave you with the video and let us know how you go.

Hi!

Thank you for your answer! I will check all this when I got the time.

But I don't think it's the cable, Since I can play videos in VLC/YT without any tearing.

I've got a bigger issue then the tearing also. My computer continues to freeze/reboot randomly. Really annoying. I think it's the motherboard that's not working as it should, since I've tried to switch all other parts (except another CPU). Different RAM, HDD/SSD, SATA-cables, fans, Power supply, etc. Nothing works. :/

However, I will try to fix this tearing anyway. Can't afford a new motherboard right now anyway (and it might not even be the problem...).

The HDMI cable doesnt look like the problem - if so the tearing would not stop rendering videos.

It looks for me more likely that theres a driver problem as there is also something marked "unloaded":

"Graphics: Card: Advanced Micro Devices [AMD/ATI] Richland [Radeon HD 8470D] bus-ID: 00:01.0
Display Server: x11 (X.Org 1.19.6 ) drivers: ati,radeon (unloaded: modesetting,fbdev,vesa)
Resolution: [email protected]
OpenGL: renderer: AMD ARUBA (DRM 2.50.0 / 4.15.0-43-generic, LLVM 6.0.0)
version: 4.3 Mesa 18.0.5 Direct Render: Yes"


On the otherhand the Mesa Driver seems ok - thats afaik the 3D-Part (OpenGL, Vulcan, whatsoever...) of the driver. As most video player make use of hardware acceleration that would also explain why video rendering doesnt cause tearing while the classical desktop rendering does.

Can you run "lsmod" and print the result? If the module is obvious "modinfo <module_name>" would even help more.

err... and as I notice just jet, am I right that there is the Radeon HD 8470D and the (IGP) A4-7300 APU with Radeon HD Graphics? Can you then check if the monitor is plugged into the motherboard or into the graphic card?
Yes, the cable doesn't seem to be the problem. Have tried another one too.

Just a thought...I have been doing gaming for many years, and have always ran a separate video card. I can get rid of the screen tears by using vsync. Have you considered going to a video card like an nVidia GTX1050? That would help with performance, and free up your memory, since you would be going through the card to process the graphics instead of using the system memory.

I am just now learning about Linux, so I can't give any solutions about command lines and so on, just what I have learned about hardware.

Just my 2 cents....

That looks or like a virtual machine to me?
I agree.

@tbtb if you are running Linux under a virtual environment, that can be a different "kettle of fish" to a full install.

Can you tell us what is the host? Is it Windows 10 or other?

Hi! It's not a virtual machine. I'm running KDE Neon on my computer. Nothing else. No virtualbox or similar.

I think it's my motherboard that's broken somehow. Since ive tried switching memory, hdd/ssd and power supply. Or could it be the CPU? Any way to check if it is the cpu? (That causes my pc to freeze/reboot, daily).

Im going to buy a new mobo soon, and would appreciate if you have any suggestions on what mobo to buy. (M-atx)

Thanks!
