Public bug reported: After successfully installing 13.04 on my Dell XPS 15z, I restarted the laptop, successfully booting into Ubuntu with no issues.
Restarting after that then gives the 'System is running in low graphics mode' message. I can only boot in recovery mode UPDATE: In the ubuntu forums thread (http://ubuntuforums.org/showthread.php?t=2115355), jbicha, recommended the following which fixed (or worked around) the problem "Perhaps this is a problem with SNA which has been enabled by default for raring. Add (or edit if it already exists) /etc/X11/xorg.conf and I think this is the code you need:" Code: Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" EndSection Extra info: This is an repost of bug 1124661 as I submitted that in recovery mode Other dell users seem to be experiencing similar issues: http://ubuntuforums.org/showthread.php?t=2115355 I installed and use the parameters mentioned here: https://wiki.ubuntu.com/HardwareSupport/Machines/Laptops/Dell/XPS/15z I have an optimus card, which the Nvidia card should be disabled as it does not work ProblemType: Bug DistroRelease: Ubuntu 13.04 Package: xorg 1:7.7+1ubuntu4 ProcVersionSignature: Ubuntu 3.8.0-6.13-generic 3.8.0-rc7 Uname: Linux 3.8.0-6-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 2.8-0ubuntu4 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true Date: Fri Feb 15 01:50:36 2013 DistUpgraded: Fresh install DistroCodename: raring DistroVariant: ubuntu ExtraDebuggingInterest: Yes, including running git bisection searches GraphicsCard: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Dell Device [1028:0446] NVIDIA Corporation GF108 [GeForce GT 540M] [10de:0df5] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Dell Device [1028:0446] InstallationDate: Installed on 2013-02-11 (3 days ago) InstallationMedia: Ubuntu 13.04 "Raring Ringtail" - Alpha amd64 (20130210) MachineType: Dell Inc.
