[Bug 153425] Re: screen shifts right when /dev/console written to
I am also having the same problem on Gutsy, and I too have a multiseat setup (two nVidia cards using the nvidia 169.09 driver). The shift only seems to happen on the first seat, although my second seat is rarely used. The shift doesn't happen very often, especially since I added the isolateDevice parameter to my gdm.conf-custom, but it does seem to happen fairly reliably upon shutdown. My guess is that the patch in the LKML thread mentioned in the original post (and present in 2.6.22, see http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=2ae854777592856ad8ce4d4cdb6114804e2e28f6) fixed most instances of the screen shift problem, but there's something about multiseat X setups that allow the occasional write to /dev/console to leak through and cause a scroll. There seems to be a few similar Ubuntu bugs (bug #75214, bug #100105, and bug #139546) but I'm guessing that kernel 2.6.22 used in Gutsy resolved those. I think that the only remaining instances of this screen shift issue are in multiseat X setups. luis: Are you still able to reproduce this in Gutsy? I can't figure out how to reproduce it. Also, would you mind changing the subject to mention multiseat so that this doesn't get marked as a duplicate to the other screen shift bugs? ** Changed in: xorg (Ubuntu) Status: Incomplete = Confirmed -- screen shifts right when /dev/console written to https://bugs.launchpad.net/bugs/153425 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

[Bug 153425] Re: screen shifts right when /dev/console written to
Thanks for your comment. Unfortunately it seems that the patch doesn't really fix this issue. I'm running 2.6.22-14, and the patch is already there (according to LXR it was put there in the first 2.6.22 kernel), but the problem persist. I'm about to reboot to try your suggestion about -sharevts, so I'll soon know if that helps. -- screen shifts right when /dev/console written to https://bugs.launchpad.net/bugs/153425 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
[Bug 153425] Re: screen shifts right when /dev/console written to
It does seem to help, but then I have to explicitly disable AIGLX in xorg.conf. It seems that it is trying to do some vt operations and then my primary screen locks up. But at least I tried writing: echo Some random text /dev/console and the secondary monitor didn't wrap, so I'm keeping my fingers crossed. -- screen shifts right when /dev/console written to https://bugs.launchpad.net/bugs/153425 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

As a workaround omitting -sharevts in the command line that starts the X server on the primary graphics card works for me (with gdm). -- screen shifts right when /dev/console written to https://bugs.launchpad.net/bugs/153425 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

[Bug 153425] Re: screen shifts right when /dev/console written to
I updated to Gutsy, and that problem went away. I believe the fix was actually in the kernel as I noticed that the fix in the vgacon.c shows up in the default Gutsy kernel. And it does make sense that it's the kernel that is allowing a leak from the console into the hardware controlled by X. -- screen shifts right when /dev/console written to https://bugs.launchpad.net/bugs/153425 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
[Bug 153425] Re: screen shifts right when /dev/console written to
I wrote to the console as root echo some random text/dev/console eight times and the screen rotated back to normal. This happened just before I took a snapshot of the Xorg log file. The date on this file is 2007-10-19 17:27, whereas I tested at 18:10, so I'm pretty sure the last messages didn't happen at the same time as the shift. I've also notice that it's not just a plain side screen rotation , but the screen actually shifts what appears to be one bit up, so that eventually you start seeing the top of the screen at the bottom.

I took this screen shot of the screen shot! The (Gnome) screen shot shows how the screen is supposed to look. When I connecte and unconnected the camera I used for this screen shot, the screen dutifully shifted right.
