Bug Description

Binary package hint: xorg

After a recent upgrade Alt-Fn and Alt-Arrow cause VT-switching. Ctrol-Alt-Fn also still works as expected.

It's fairly disruptive, would love to either fix it or find a workaround. please let me know if there's anything i can do. it may be related to this bug which appeared at the same time:

found some ancient redhat bug reports that seem to be of the same behaviour, not sure if the discussion there will help with diagnosis?

BTW, restarting X helps until next reboot...

Same problem here but it appeared just after installing and booting tuxonice kernel (2.6.32-24-generic-tuxonice #38~ppa1-Ubuntu SMP)

I've found somewhere a solution. After commenting out:

in my xorg.conf everything's working fine.

Have you tried 10.10/11.04 to see if this still happens?

Fixed for now by editing /usr/bin/startx and passing in "-retro" to serverargs: Код:

Experiencing the very same problem with 11.10. Used it since Alpha, bug appeared sometime in beta phase IIRC.

Currently experiencing this problem on 12.04 with nvidia driver. Impossible to tell if it's really the same bug or just the same symptom from the little information we have so far. I can't recall ever expericing this problem in the past.

Matt Price, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-input-evdev REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.
