Bug Description
Binary package hint: vbetool
HW: HP nw8440 laptop with ATI Technologies Inc M56P [Radeon Mobility X1600]
SW: Kubuntu/Jaunty, up-to-date, using FOSS ATI driver
I wanted to contribute to suspend testing, therefore I hav run the script provided here:
https:/
Laptop suspends fine, it also auto-resumes after 10 sec timeout, but I end up with blank screen. As keyboard is working (CapsLock turns LED on/off), I have tried to switch consoles (Ctrl-Alt-F1 / Ctrl-Alt-F7), which got me back to my KDE desktop (properly protected by lock).
CPU load was high (1 core was 100%), generated by "vbetool" process. If I have continued the test (with next suspend cycle), it failed to suspend. If I kill the "vbetool" process (which requires another console switch to get back to normal KDE desktop), then next suspend will work and resume will behave the same (blank screen, console-switch needed, have to kill vbetool, another console-switch needed).
It looks like this "vbetool" is causing problems to my system.

It seems that wrong hal-info quirks are set for this laptop. Changing package to hal-info.
