I have dual boot arch linux with Windows 8. I have AMD Radeon GPU. Recently, my GPU has broken. And now, I cannot boot into my arch linux. I am able to boot into live CD, and it says: "disabling GPU acceleration"

I can also boot into Windows by disabling the GPU acceleration via device manager. I am unable to disable GPU acceleration in my linux manually.

I couldn't find the solutions in the internet. So, is there a way to disable my GPU acceleration in Arch?


  • You can prevent a module from being loaded by passing modprobe.blacklist=KO_NAME on the kernel command line. After the first boot, blacklist it permanently using modprobe.d(5). Since you’re using Arch, you may have to adjust your mkinitcpio.conf(5) as well, cf. wiki.archlinux.org/index.php/kernel_modules#Blacklisting – phg Feb 6 '17 at 14:24
  • I tried blacklist fglrx, blacklist radeon, alias radeon off, and alias lbm-radeon off in blacklist.conf as suggested in askubuntu. But this led to fatal server error: (EE) Cannot run in framebuffer mode... error while starting X server. – xer0.5ive Feb 6 '17 at 14:34
  • It worked after loading radeon module. Thanks!! – xer0.5ive Feb 6 '17 at 15:36
