[Bug 176515] Re: [Hardy] Race condition in Xgl startup process
As of today's updates (including an upgrade of the kernel), Xgl seems to be working well. Haven't been able to figure out what exactly put things right.

[Bug 176515] Re: [Hardy] Race condition in Xgl startup process
Ooops... Jumped the gun there. Though fglrxinfo was reporting that the appropriate driver was in use, I found the graphics to be a bit too slow. So I checked glxgears and found that I was getting frame rates of ~300. I reinstalled the ATI driver (8.01) only to find that the blank screen on login as before. .xsession-errors ends with the line 'Waiting 10 seconds for Xgl to start'. Nothing more. FWIW: Was also getting a gnome-settings-daemon error at startup (bug 199960). Have now reverted to no Xgl and metacity. Performance is back to normal (1700 fps in glxgears). -- [Hardy] Race condition in Xgl startup process https://bugs.launchpad.net/bugs/176515 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Wanted to confirm hnmb's point: The updated xserver-xgl has not solved the problem in my computer. Have reinstalled (and now updated) gdm, but the system continues to pause at gdm load when xserver-xgl is enabled.

I found some spare time to look at it. Applications started within the session, always stuck in select, endlessly waiting for a response in my case.

Your patch seems a fine solution for this problem. I'll look at adding something like this to the scripts sometime over the holidays, but don't hold your breath too soon!

My very first debdiff attempt. Hope I did it fine. @Slash123 : It seems to be a pb with your gnome session. look into ~/.gnome2/session or try removing your ~/.gnome2 directory to see if it solves it.

[Bug 176515] Re: [Hardy] Race condition in Xgl startup process
Great. I got Xgl to load on DISPLAY :1 using your Xgl-session attachment. However, gnome (or for that matter KDE) refused to start. On entering login details, I can see the hard disk activity till Xgl loads, then it just stops with the human background and a busy pointer. I noticed that if I run compiz from tty1 (# DISPLAY=:1 compiz ), compiz finds Xgl and loads without an error, but still no desktop. However, if I run # DISPLAY =:0 xterm, I get an xterm on vt7. I can then start gnome-panel and nautlius to have a working gnome session. But, as this is :0 (whereas Xgl loaded on :1), when I try running compiz from this xterm, it exits with an error that it couldnt find Xgl. ~/.xsession-errors now does not have any errors that could give a clue. Neither does /var/log/Xorg.0.log.

[Bug 176515] Re: [Hardy] Race condition in Xgl startup process
I'm having a similar error in Hardy (cannot open display :1) Could you elaborate on this patch please? 1) My guess is that the line about seahorse in your .xsession-error is unrelated. Correct? 2) Where in /usr/share/xserver-xgl/Xgl-session should the code you added above be pasted? Could you provide the contents of the previous and following lines? I tried adding the commands between: ... verbose Starting Xgl with options: $XGL_ACCEL_OPTS $XGL_OPTS \n $XGL_WRAPPER $XGL_DISPLAY $XGL_ACCEL_OPTS $XGL_OPTS DISPLAY=$XGL_DISPLAY and #Don't use Shift+Backspace as terminate_server xmodmap -e keycode 22 = BackSpace else ... But the patch did not seem to help. On logging in, the system just paused. Admittedly, I did not get the error in .xsession-errors, but Gnome did not load and the PC just waited. I had to disable Xgl (reinstating the file 'disable' in ~/.config/xserver-xgl) to login as usual. If possible, please attach a copy of your Xgl-session that works. My config: Hardy Compaq nc6230 ATI Mobility radeon Thanks!

[Bug 176515] Re: [Hardy] Race condition in Xgl startup process
Sorry, in the hurry I forgot to post the file. Here is the modified version of Xgl-session The command /usr/bin/seahorse-agent --execute /usr/bin/gnome-session is passed as argument to the Xgl-session script and executed at the end. If the display in $DISPLAY is not ready the command fails with can't open display and gnome-session is not executed. Adding traces to this script, I've observed that the exec $@ is executed _before_ the Xgl command in the wrapper script Xgl-lockfile- wrapper (except the first time you log in). In this case the session can't start because the display is not ready. My .xsession-errors was similar to the one of Bug 174408. The wait loop added to the startup script also solved the xmodmap error. ** Attachment added: Xgl-session http://launchpadlibrarian.net/10928340/Xgl-session -- [Hardy] Race condition in Xgl startup process https://bugs.launchpad.net/bugs/176515 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
