I bought a used Gigabyte Windforce R9 290 OC graphics card off eBay recently, and was wondering whether it in fact was broken or I am doing something wrong. I am not able to seem to get it working.
If I have the graphics card in the computer, the installer doesn't seem to load (black screen), so I take it out to install. Then I make sure I update & upgrade everything. I then tried rebooting with the GPU installed but again a black screen. I tried downloading the AMD proprietary drivers from their site, tried both their .deb & .run files and neither actually installed (likely as I didn't have the graphics card installed). So I booted with 'nomodeset' to try and get in to install drivers. This worked, although at some tiny resolution and random green flashing (like a semi-transparent layer of green). I installed the AMD for Linux (.run) driver fine, so disabled nomodeset and rebooted. Black screen again. I re-enabled nomodeset, this time it booted at the right resolution (1920x1080), except there were green flashes, especially on animating windows (haven't tried any games yet).
I tried installing Windows 10 on the computer without the graphics card and it worked fine, so installed the graphics card but then ended up with a low (1024*768) resolution, using the default Microsoft drivers. I managed to install the catalyst drivers and it work fine, but with green flashes again except much rarer (once every minute, not every time I resize a window).
My specs are:
- Gigabyte Windforce R9 290 OC
- Samsung 850 EVO 500GB
- 16GB HyperX DDR3
- EVGA 600W PSU
Thanks in advance!
