Today, with Xdiagnose unused, I again had an error message "Running in Low Graphics Mode", after about a dozen starts with no problem.
I again engaged Xdiagnose, checked the top 3 boxes about functions, and also engaged "Disable bootloader graphics". Back to checking results... -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1772386 Title: message - Low Graphics mode - about 2/3 of startups - not all Status in xorg package in Ubuntu: Incomplete Bug description: After a recent update (kernel?), I have begun to occasionally receive the message "Running in Low Graphics Mode" at boot (maybe half the time). I can tell it to use Default setting from the options it offers, and get by it, after which things look and work normally until a reboot, which may or may not occur correctly. I also usually get "System error detected, Report? at the same time, so I agree to report it. Please note that I'm using 16.04 (fully updated), Gnome Flashback Metacity, with [AMD/ATI] Cape Verde PRO [Radeon HD 7750/8740 / R7 250E] . This problem shows up no matter which of the above I'm using, or Unity. roger@roger-desktop:~$ uname -a Linux roger-desktop 4.4.0-124-generic #148-Ubuntu SMP Wed May 2 13:00:18 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux roger@roger-desktop:~$ free -m total used free shared buff/cache available Mem: 16013 3880 10410 363 1722 11443 Swap: 16348 0 16348 roger@roger-desktop:~$ df -h Filesystem Size Used Avail Use% Mounted on udev 7.8G 0 7.8G 0% /dev tmpfs 1.6G 9.6M 1.6G 1% /run /dev/sda1 902G 77G 779G 9% / tmpfs 7.9G 127M 7.7G 2% /dev/shm tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs 7.9G 0 7.9G 0% /sys/fs/cgroup cgmfs 100K 0 100K 0% /run/cgmanager/fs tmpfs 1.6G 52K 1.6G 1% /run/user/1000 I have found a WORK-AROUND. Using x-diagnose, I selected all options under both Debug and Workarounds. After this, all works normally every time. However, I take this as a crutch, not a fix, and think other action should be taken Selecting "View Errors" shows no errors, so I never tried reporting from that point. This gives me a presumption that there is a bug in coding that interacts badly with my system and a few others like it, which I encountered in my search for a solution. Also, if I simply go to 18.04 (I don't really want to just yet.) will it likely fix this or might this block or damage the upgrade? 1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu roger@roger-desktop:~$ lsb_release -rd Description: Ubuntu 16.04.4 LTS Release: 16.04 2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center roger@roger-desktop:~$ apt-cache policy pkgname N: Unable to locate package pkgname ALSO - I'm unable to locate this information in Software Center 3) What you expected to happen Normal boot, no errors or problems 4) What happened instead "Running in Low Graphics Mode" displayed, along with subsequent "System Error Detected" messages ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: xorg 1:7.7+13ubuntu3 ProcVersionSignature: Ubuntu 4.4.0-124.148-generic 4.4.117 Uname: Linux 4.4.0-124-generic x86_64 .tmp.unity_support_test.0: ApportVersion: 2.20.1-0ubuntu2.17 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None CurrentDesktop: GNOME-Flashback:Unity Date: Mon May 21 01:56:23 2018 DistUpgraded: 2016-12-17 18:57:41,412 DEBUG icon theme changed, re-reading DistroCodename: xenial DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: Advanced Micro Devices, Inc.
