sysrq and screenshot use the same keyboard shortcut

[Gonzhauser]

I want to kill a runaway process even if X doesn't respond with Alt-Sysrq-F.
CONFIG_MAGIC_SYSRQ in Ubuntu is enabled.
But pressing Alt-Sysrq-F to invoke the oom killer also opens the Gnome Screenshot Dialog which uses Alt-Sysrq.

I expected two different shortcuts for two different actions.

Hi gonzhauser,

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with the latest development release of Ubuntu? (ISOs are available from cdimage.ubuntu.com)

If it remains an issue, could you also attach a new /var/log/Xorg.0.log?
Thanks in advance.

The output of lspci -vvnn would also be worth having.

I can confirm this issue is occurring, however this mapping is not done by xkeyboard-config

Similar problem,
But pressing Alt-Sysrq-F opens the Gnome Screenshot Dialog only.

the screenshot shortcut is alt-printscreen but printscreen and sysrq are often the same key

[Sebastien Bacher (seb128)]

that's not really a bug, does anybody has a suggestion on how you would change those to not conflict?

[Gonzhauser (gonzhauser)]

It's even worse: I tried to disable alt-printscreen in system->settings->keyboard and the gnome-screenshot window still comes up. Even disabling printscreen in the keyboard settings doesn't help.

I'm still seeing it in Jaunty, and my SysRq and PrtSc keys are two separate keys. Also, I gave PrtSc set to activate *on its own* not in combination with Alt.

@Gonzhauser: You have to restart X for those changes to take effect.

@BUGabundo: Any idea what patch fixed this for you? I'd like to be able to backport it to 8.10...

scrash that! i getting an huge amount of popups once i hit Fn+alt+SysRq

[Sebastien Bacher (seb128)]

that's not a GNOME issue but a keyboard layout one

[PetiePooo (petiepooo)]

Sebastien,
I agree that this is a keyboard mapping issue. If not gnome-control-center, what module would I open this bug against?

it appears to be 'fixed' in maverick ... so ppl now complain about not getting those popups :-/
see bug 642792

[Fernando Miguel (fernandomiguel)]

seems fixed in Natty

[ski (skibrianski)]

On Lucid (and probably earlier versions), you can disable the alt+print keyboard shortcut in system->preferences->keyboard shortcuts seems to do the trick. You could probably change it to ctrl+print or something, but I didn't bother since I don't use that feature enough to care. Cheers all.
