Bug 147128 – xorg-x11-7.1 - starting a second X session and exiting from it results in a locked up keyboard/mouse/display

• Status: RESOLVED NEEDINFO
• Product: Gentoo Linux

[Description Dima Ryazanov 2006-09-10 22:48:51 UTC]

I am using xorg-x11-7.1, with xf86-video-ati-6.6.2.

I start a second X server, e.g. using "xinit /usr/bin/startfluxbox -- :1 -nolisten tcp", and then exit from it (e.g., exit from fluxbox). I get a blank screen, and keyboard and mouse don't work anymore. I can't switch to another terminal using Ctrl-Alt-F#, etc.

If I login from another computer, I can see that everything is running fine, and the second X server is gone. If I run "chvt 1", it freezes while calling "ioctl(fd, VT_WAITACTIVE, num)".

When I ran "DISPLAY=:0 kdeinit_shutdown" (I'm using KDE), X unfroze almost immediately - everything came back, and I could see applications closing.

I run into the problem with broken VT switching pretty often. Even a program that takes over the whole screen can easily cause that (e.g., a Windows game running in Wine) - not just playing with multiple X servers.

What video card do you have?  Also, do you have AIGLX enabled?

Some of these issues sound like things that may be fixed in the masked version of xorg-server.  We're waiting on Mesa's 6.5.1 release to make it available.

[Comment 3 Dima Ryazanov 2006-09-14 14:00:41 UTC]

I have Radeon 7000. I don't think I have AIGLX - at least, I didn't enable anything like that. I do use EXA, though.

I'll try the masked xorg...

[Comment 4 Joshua Baergen (RETIRED) 2006-09-24 10:21:31 UTC]

xorg-server-1.1.1-r1 is out of hard mask now.  Give that a try.  Try disabling EXA as well and seeing if that helps.

Re-open the bug when you've done so.
