Usplash causes machine to hang on shutdown/reboot

[Matt]

I recently upgraded my Kubuntu installation to Dapper, but since then I've been having problems sometimes with the machine hanging on shutdown.

It occurs just about the point where X-Windows closes and Usplash takes over the screen. Quite frequently, the screen will go blank and the machine stops responding to input.

On occasions that the machine does shutdown/reboot, the usplash screen will appear, but approx 70% of the time, the Kubuntu graphic appears corrupted (green blocks across the screen, things like that).

This made me think that maybe Usplash is experiencing some form of corruption, so I uninstalled it. The machine now shuts down fine each time.

It might be a problem with the interaction between Usplash and X-Windows, because I am running the ATi fglrx driver from the restricted dpkgs on my Radeon 9600.

On the occasions that the machine doesn't /appear/ to be shutting down. Could you try leaving it 5 minutes and see if it did infact power-off in the end?

Could you also check whether this problem occurs using the open-source 'ati' driver, instead of the 'fglrx'.

These two points should help to track down the likely causes.

After reinstalling Usplash, the failure to shutdown is not as common anymore, but does occasionally still happen. I left the machine for half an hour, once the blank screen appeared and nothing happened.

I've not yet had a chance to change the X server driver, I'll try and do that tonight and see what results that brings.

I changed to using the 'ati' driver and the machine no longer hangs on shutdown or reboot. Nothing appears on the screen until "Resetting remote filesystems" appears on the screen though, but shutdown or reboot is successful everytime.

[Matt (matt-madskills)]

Of course, that should read "Unmounting remote filesystems".

Some of the Ati hang ups might be related to http://ati.cchtml.com/show_bug.cgi?id=239

After a lot of playing, I believe this is a problem with the Ati driver and not usplash. Hence this is a duplicate
