(Solved) Recommend GPU for older setup that will work in Linux Mint 19.3

Thanks again for your time. the HD 4670 is an old card and has its limitations compared to current specs but works fine for my requirements. I dont think it will run Eyefinity but I have not had the need to try it. It only has an HDMI port on the back (alongside DVI & VGA).

The dual monitor setup works perfectly fine in windows 7. I use the Ati Catalyst software to setup the two monitors.

I thought I’d try running a live version of LM 19.3 to see if it would natively recognise the two monitors with the primary monitor connected via DVI and the Tv connected by HDMI (when set up in this way the installed LM freezes - so I substitute the HDMI with VGA and it works). I was therefore surprised that the live version didn’t crash but only displays the same graphics on both the monitor and TV. I ran inxi -G
mint@mint:~$ inxi -G
Graphics:
Device-1: AMD RV730 XT [Radeon HD 4670] driver: N/A
Display: x11 server: X.Org 1.20.4 driver: vesa resolution: 720x400~N/A
OpenGL: renderer: llvmpipe (LLVM 8.0 128 bits) v: 3.3 Mesa 19.

I then rebooted with the hdmi connected to tv. After logging in, all I got was a black screen on both the monitor and the tv. I pulled the hdmi cable out and the system appeared on the monitor.The HDMI out literally chokes the system.

I ran inxi -Gx
~$ inxi -Gx
Graphics:
Device-1: AMD RV730 XT [Radeon HD 4670] vendor: PC Partner Limited
driver: radeon v: kernel bus ID: 01:00.0
Display: x11 server: X.Org 1.20.5 driver: ati,radeon
unloaded: fbdev,modesetting,vesa resolution: 1680x1050~60Hz
OpenGL: renderer: AMD RV730 (DRM 2.50.0 / 4.15.0-74-generic LLVM 9.0.0)
v: 3.3 Mesa 19.2.8 direct render: Yes

The fact that I can use the HDMI to the TV in the live scenario gave me hope that there is some way I
can get the setup to work. I realise the simplest solution is to replace the GPU but with my motherboard (AMD AM3) this is not so easy as many, relatively, newer GPUs aren’t compatible with the legacy BIOS and buying an older used card is always a risk. So I am a bit stuck.
I read a lot of articles online last night about getting and setting up dual monitors on Linux.
Unfortunately, I didn't get really good detailed information to solve the issue you are having.
I had hoped to.

Brand new GPU's can be expensive especially if you weren't prepared for it.

Would a newer GPU not be compatible with your BIOS and that's why your stuck?
(trying to understand)

Hi I’m stuck on both counts: I cant get my current gpu to work as I want it to and newer cards may not be compatible with my motherboard/BIOS. I have researched into different brands of 1050ti cards I have decided on an Evga which i have been informed is compatible. I will no doubt need help setting it up getting Nvida to work with Linux. Thanks again for your all your help.

Good to hear your going with EVGA. That's a good brand. I learned that from a man that builds pc's. His name is Carey Holzman. He's on Youtube.

With Nvidia all you have to do is download the driver for your GPU from the Nvidia website and run the .run file to get it installed. The installer will walk you through it.

Just let us know the exact GPU you purchase and we can help you find the driver.
 
I have installed an Evga 1050ti SC and it works fine. I can use the latest Linux kernel and have set up the dual monitors with DVi & HDMI and everything seems stable. Thank you so much for your support in this matter, I appreciate all your time and effort.

Your Welcome-:)

Glad to hear your new EVGA GPU did just what you needed.

Don't forget to go to the first thread you made and mark it SOLVED.
