I'm experiencing a problem in Ubuntu 12.04.3 LTS. I have an ATI Radeon 9100 (r200), which supports 3D acceleration as you can verify by $ glxinfo | grep direct direct rendering: Yes and is using the xserver-xorg-video-ati / xserver-xorg-video-radeon driver. Anyway, after some upgrades time ago, lightdm started to not recognize graphics capability: when I power up the pc, I got a "The system is running in low graphics mode" error. I tried to reconfigure the package and many other solutions I've seen around the internet, but I couldn't solve it. The only workaround, which also justifies why I selected "lightdm" package and not "xserver-xorg-video-ati" package, was to switch logon screen from lightdm to gdm: GDM correctly recognizes the 3D ability and gives no error. Steps to reproduce the bug: 1- Install an ATI Radeon 9100 card 2- Install Ubuntu 32bit 12.04.3 LTS (lightdm v.1.2.3-ubuntu2.3, xserver-xorg-video-radeon v1:6-14.99~git20111219.aacbd629-0ubuntu2) 3- Start the computer. I may suggest, though I'm not so sure, it could be a regression? https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- ati/+bug/495973 Thanks in advance, Rob ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: lightdm 1.2.3-0ubuntu2.3 ProcVersionSignature: Ubuntu 3.2.0-52.78-generic 3.2.48 Uname: Linux 3.2.0-52-generic i686 ApportVersion: 2.0.1-0ubuntu17.4 Architecture: i386 Date: Tue Aug 27 14:07:12 2013 MarkForUpload: True ProcEnviron: LANGUAGE=it:en TERM=xterm PATH=(custom, no user) LANG=it_IT.UTF-8 SHELL=/bin/bash SourcePackage: lightdm UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1217378/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
