Gnome brightness keybinding OSD locks interface

[Sb]

Hello,

I have Ubuntu 8.10 on a Dell Inspiron B130 (1300) laptop. When I use the hardware brightness control (Fn+ Arrow Up/Down) with Gnome running, the OSD pops up and moves erratically, and then most elements of the interface lock up, including the keyboard and most of the icons fail to respond. The OSD brightness indicator does not go away either. I have to Ctl+Alt+Backspace to restart X. The volume control OSD works correctly as expected. The brightness controls function normally when I am not running Gnome. Additionally, the Gnome brighness panel applet causes the same interface lockup problems. I did not have this issue with Ubuntu 8.04.

Thanks for the help!

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage . I have classified this bug as a bug in gnome-power-manager.
For future reference you might be interested to know that a lot of applications have bug reporting functionality built in to them. This can be accessed via the Report a Problem option in the Help menu for the application with which you are having an issue. You can learn more about this feature at https://wiki.ubuntu.com/ReportingBugs.
Also, I've been unable to reproduce your issue on Ubuntu 8.10. Can you reproduce this issue with an Ubuntu LIVE CD and report back if the problem still exists on Ubuntu 8.10 LIVE CD?

I've tried this on a Dell XPS M1730 running nVidia Corporation GeForce 8800M GTX and the latest Ubuntu 8.10 updates.

Hello, thanks for looking into this.

Sorry, I do not have the Ubuntu live CD, I installed from the alternate install CD. My internet connection is slow and unreliable, so I can't download the live CD right now. I should have mentioned that my laptop has Intel 915 graphics. I don't think gnome-power-manager has error reporting built in.

Anything else I can do to help? Thanks!

Could you please attach the resulting log file of:

gnome-power-bugreport.sh &> gpm.log

to the report? You might also want to take a look to the Debugging instructions located at https://wiki.ubuntu.com/DebuggingGNOMEPowerManager for submit any other logs related to your problem. Thanks in advance.

[Sb (sb56637)]

Ok, here's the log of:
gnome-power-bugreport.sh &> gpm.log

[Sb (sb56637)]

And here's the log of:
dbus-monitor --session "type='signal',interface='org.freedesktop.PowerManagement.Backlight'"

If you grab the kernel from proposed and it fixes it, you've got a duplicate of bug 261721

[Sb (sb56637)]

OK, good, the update to kernel 2.6.27-8 fixed it. Thanks!

Sb,

Ctrl+Alt+F2 will fix X but not kill everything (and require you to log back
in)
if it has gotten to a state where Ctrl+Alt+F2 drops you to a command line
login, then hit Ctrl+Alt+F6 or Ctrl+Alt+F7 and it will take you back to X,
fixed.

best of luck
