I have downloaded Ubuntu 14.04 and wanted to try some OpenGL programming. My laptop has switchable graphics technology (Intel HD Graphics 4000 and AMD Radeon HD 8570M). I thought that it'd be better to install proprietary drivers and take advantage of OpenGL 4+ so first I installed the drivers by typing sudo apt-get install fglrx-updates, then I rebooted my pc. However, after boot, low-graphics error came up instead of login screen.

I didn't give up and tried searching google on my other computer. I tried almost everything possible, yet it still looks like my graphics is not being recognized.

It's worth noting that I have linux-headers installed and am using 64bit version of Ubuntu. Also, when I uninstall the fglrx driver, everything works fine again.

Here's what I already tried:

  • Reinstalling the drivers (complete purge).
  • Entering low-graphics mode and typing amdconfig --initial.
  • Installing the newest drivers drivers from amd.com (I also tried beta drivers; no luck).
  • I switched LightDM to GDM, still no luck (it completely broke my Ubuntu installation).

Thank you for any suggestion.

EDIT: By reading some log files I came to a conclusion that the greeter fails to start. I just don't know why.

EDIT 2: I installed GDM once again. Now it boots to console without showing any error. I tried to log in and type startx and it says Caught signal 11 (Segmentation failed).

Zanna

  • Unfortunately, it didn't work for me. The low-resolution graphics error still comes up. – michy04 May 08 '14 at 08:02
  • Mmmm...Then to solve low graphics error you can follow this: http://askubuntu.com/questions/141606/how-to-fix-the-system-is-running-in-low-graphics-mode-error Don't fail to see Jokerdino's answer there. It addresses your greeter issue. – Venkatesh May 08 '14 at 08:51
  • I already check that. The problem is that ubuntu-greeter is already there. – michy04 May 08 '14 at 09:16
  • Post your ' /usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf ' file. – Venkatesh May 08 '14 at 09:18
  • The 50-ubuntu.conf is almost empty. Here it is, anyway - http://pastebin.com/txu3tJ2F – michy04 May 08 '14 at 09:26
  • Try adding this line to that file: greeter-session=unity-greeter BTW reconfigure lightdm before trying it. – Venkatesh May 08 '14 at 10:07
  • I have tried that. Doesn't work. Linux is great, there's just always something that prevents me from using it to its full potential... – michy04 May 08 '14 at 10:29
  • Uhh... I have moved this to chat and pinged you in the chatroom... weren't you notified? – Venkatesh May 08 '14 at 10:30
