Upgrading video card. How to?

Post by redbiker » Mon Aug 05, 2019 10:36 am

Going to replace my Radeon card with a Nvidia Card. I am unable to get full resolution on my widescreen LG 29WK500-P.
Do I just just install and boot, or do I need to do anything to the system first?

Sorry for the basic question. Still learning.

Running Cinnamon 19.2.

Have you verified that your Radeon will not do that ultrawide resolution on Windows neither? If it does, you'll be able to get it going. Other than that, yes, assuming we're not talking about an old 17.x install with the old Radeon Catalyst driver installed, change cards and boot. This'll have the new card use the open "nouveau" driver; you may (or may not...) want to switch to the proprietary Nvidia driver through Driver Manager afterwards. If "nouveau" gives you trouble upon reboot, boot with "nomodeset" (search this forum or google) and certainly install the proprietary Nvidia driver.

Tried everything to get the 2560x1080 resolution. Open driver doesn't support it.
Going to buy a NVIDIA GeForce GT 1030 2GB GDDR5 PCI Express 3.0 card. Claims to support Linux.
Not gaming. Just want full resolution.

Seeing as how you "tried everything" you probably tried this: https://askubuntu.com/questions/1125783 ... h-amd-card, but I'd still be surprised if you couldn't get things going. Which isn't to say that electing for Just Works can not be sensible. In that context though, newer AMD cards (GCN 1.2+ or RDNA) in fact enjoy better Linux support than Nvidia's...

Note; the link's advise is good for testing but would need to be made permanent if it works. Via xorg.conf.d configuration is probably (still) the best method; I'll ty and advise if indeed it does work.

When I run xrandr --addmode HDMI-0 2560x1080_60, the screen goes black, and system locks up.
HDMI-0 is the correct setting.

Usually that's on laptops an issue with first having to disable the laptop screen but giving that you're considering replacing the card I assume we're talking about a desktop here. Am afraid this region quickly gets hard to debug over the internet (i.e., trial & error works best locally); you might indeed be best of with another card, especially if (as is assumed) the current radeon is very old in the first place.

I tend to agree.

Thank you so much though!
