need help with a amd onboard gpu
by rKellerm from LinuxQuestions.org on (#5390S)
I am new to the linux world and especially the hardware stuff. I know there are probably answers on this forum somewhere but it's hard to find. Basically I have centos 7 I think it says it's 3.10.0-1127.el.x86_64, not even sure if that's the version of kernel or what.
In a nutshell I have an onboard amd gpu.
I ran this :grep -E 'VGA|Display' and it says:
01:05.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] RS880 [Radeon HD 4250].
I installed drivers from amd site but nothing is working like it should. when i try to change the display setting it says its an "unknown monitor".
running this returns:
xrandr | grep -w connected
xrandr: Failed to get size of gamma for output default
default connected primary 1024x768+0+0 0mm x 0mm
So I don't know what to do to fix this stuff. The amd driver installed but evidently it's not loading? I've tried a ton of stuff from all the web sites I can find. Nothing works. I'm new to linux and don't quite understand what drivers to use or if I need to install any other than default one included with centos. Please help me I'm really lost on this one.
