Reboot/Shutdown problem after upgrade to 10.04

[diyu01]

Hi, I have recently upgraded to 10.04 through package manager. After a long process, the upgrade process tells me "upgrade completed but failed", then I tried to reboot my computer, it spat out a lot of error messages but successfully rebooted at the end, and I see 2.6.32 kernel options added to my boot menu. I selected that option, and successfully logged into the system with a new look, and the system seems to work fine. However, when I tried to choose "reboot" or "shutdown" from the new system, it always goes into black screen very quickly but then hangs after that (the computer stays powered up, but the screen shows nothing), and I had to manually reset the computer.
Also, when I reboot into the new system, I noticed that there is no splash screen, the screen just stays black for a long time and then shows something like "MMIO failed" and switches to the login screen.
The system seems usable but the inability to reboot/shutdown is bothering me. Is there any way to fix that? And is there any way to get the splash screen to work again? Thanks!

Re: Reboot/Shutdown problem after upgrade to 10.04

After getting into your desktop, open a console and run:

sudo dpkg --configure -a

then:

sudo apt-get update

then:

sudo apt-get dist-upgrade

See if this helps fix things.

Hi, I did those steps, they all finished very quickly and without error, but I still cannot reboot/shutdown properly (the symptom was still that after I chose "reboot" or "shutdown" from the menu, the display turns black very quickly, but the box stays powered on). Thanks.

I have the same problem from both upgrade and fresh install and on both ubuntu and kubuntu. It always happen to me after I install the nvidia drivers from both the nvidia site and the hardware drivers. I also hear several beeps when shutting down, restarting, logging, and ctrl+alt+(F1,F2 etc) then followed by a black screen.
When I run the code:

sudo shutdown -r now

It reboots(still with the multiple beeps)
When I run the code:

sudo halt

It shutdowns (still with multiple beeps)

Strange thing while I had the same problem in Ubuntu 10.04 I used the first code and it shutdown my PC completely. After using the code I was able to shutdown via the task bar like normal but this isn't the case in Kubuntu as of yet.

Re: Reboot/Shutdown problem after upgrade to 10.04

I tried

sudo shutdown -r now

and it behaved worse: the screen went black, but the light indicator shows that it still gets signal from the box (just that the signal is a black screen). Also, the box stays on. In the previous try, when I invoked reboot from the menu, at least the screen does not get any signal from box.

Thanks.
