"Magic SysRq keys" don't work on laptop (Dell XPS M1210)

[zorblek]

After reading about the "Magic SysRq key" combinations, I have attempted to use them several times when my laptop (a Dell XPS M1210) has crashed for various reasons, and they have never worked. The specific sequences I've tried were REISUB and RSEIUB, and neither had any visible effect.

This may have something to do with the keyboard layout. It's more or less a normal QWERTY, but several keys share space, including SysRq, which is on F11. To switch between them there is a Fn key which must be pressed. So in theory, the full key combo would actually be Alt+Fn+F11/SysRq+R and so on. But this doesn't seem to work. I've also tried it without the Fn key, and that doesn't seem to work either. I don't have a USB keyboard available, so I don't know if it works with another keyboard attached.

If there's any other useful information I can give you, let me know.

No, this is different. PrntScrn and SysRq are on the same button, but I can
use them separately. To use PrntScrn, I have to hold Shift in addition to
Fn. Otherwise it registers as SysRq.

Did you try this key combinations in a system console (press ctrl+alt+f1)? If this works for you, this bug is maybe a duplicate of bug 305762 and affects only xorg.

[zorblek (zorblek)]

All that happened was that I got this output to the command line:

SysRq : Changing Loglevel
Loglevel set to 5
SysRq : Changing Loglevel
Loglevel set to 4

I got the same result both while pressing and not pressing Shift.

Hi zorblek,

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? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/lucid.

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

apport-collect -p linux 315503

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

I (thought) i had this bug too.

When i press Alt+Fn+delete/sysrq+R i got gnome-screenshot all over the place.
When i press Fn+Alt+delete/sysrq+R i got the sysrq event

So (for me) the problem isn't the combination itself, but the order i have to press them. Maybe the same problem applies to zorblek.

The order of pressing buttons, is that normal behaviour or should i create a new bug for it?
