Plymouth kills my video card upon shutdown

[bamyasi]

Hi,

After seemingly smooth upgrade from 9.10, every time I now shut the system down my video card gets killed. I hear 4 beeps from the motherboard (long+3 short ones pattern) and then my monitor shuts off immediately with "no video signal" message. On the next boot, there is no video signal at all and the monitor stays off (although the system seems to keep booting). The only way to restore the video card functionality is to power-cycle the system.

With so many complaints about numerous Plymouth issues on the net, Google is unfortunately of little help. Any advice, anyone?

This system is Core i7 940 / X58 (ASUS P6T Deluxe) with ATI Radeon HD 4850 card, open source radeon driver (NOT fglrx).

Thanks!

OK, did a bit of investigation and it looks like that only system reboot results in the video card permanently disabled, while system halt does not. Either KDE "Restart Computer" option or "shutdown -r now" console command would kill the video. KDE menu option "Turn Off Computer" as well as "shutdown -h now" both work as expected and computer will boot afterwards without the need to power cycle it.

Re: Plymouth kills my video card upon shutdown

Attempted playing a video clip via smplayer today and it eventually killed my video card too. First the keyboard started to misbehave -- lost control/alt keys, then monitor just shut off with "no video signal". Next time I rebooted after power-cycling my computer I had a corrupted mouse cursor in KDE (blinking garbage). Had to shut computer down, kill the PSU power switch and wait for 30 minutes to get rid of this. Looks like open source ATI/radeon driver is definitely not ready for the prime time.
