I tired posting this on the Ubunutu forums first with no useful response
I've recently installed Xubuntu 8.04 after liking the live CD of Ubunut and I heard that XFCE was "lighter."
Well I'm having one fairly large problem. When I shutdown the computer it never actually shuts down. It shows a few lines of text, nothing that at least appears to be an error to me, then a flash screen shows up that just says XUBUNTU with a mouse, similar to that that at the loading screen, and that is as far as it gets, it never finishes the shut down. When I eventually power it down manually I don't feel as though I'm loosing any saved information, though it seems like its running a bit slower. I have no problem using the RESTART option nor the LOG OUT option.
How can i fix this?
After a while I stopped worrying about it and just went about like normal, shutting the PC down manually whenever this "lock out" happened. My first thought was "perhaps this is like the 'your computer is now safe to shut down' screen from the windoze 95 days"
now the problem has gotten way worse, anytime i don't do anything for a while, like if i wonder away from my PC while its running Opera or Firefox, the computer just feezes, I can't get it to respond to an keyboard commands like CTRL-ALT-ESC or CTRL-ALT-BACKSPACE.
What's the best way to fix this, I can exit X and run from the command line with little troule
My first thought would be that either you don't have ACPI enabled or that it's not working right. I don't use Ubuntu or any of it's cousins so I don't know where to tell you to look but if you search for ACPI you should be able to figure it out. As far as using the command line to turn off or restart your computer the answer is yes you can. All you have to do is type either "poweroff" or "reboot" and you are all set.
I would also check the BIOS to see if you have your ACPI settings set up right.
My other thought comes from you saying that now applications freeze. I've seen this many times in laptops that are either old or have been mis-treated. Sometimes you get bad sectors on the hard drive and you will need to run some sort of physical check to see if there are any bad areas. If you are still running the live CD which I was unclear if you were or not, your CD may just be dirty or scratched. You could also try cleaning the drive. Did you verify the MD5 sum before you burned the .iso? Your installation may have been corrupted.
Forgive me for my from the beginning approach here but I am an old school hardware guy. If it were my computer I would first disable ACPI just for fun to see if anything changes. If it continues then I would re-enable ACPI and move on to removing all expansion cards and things like printers. I might even remove a fancy video card and go back to the on-board video. At this point I would try to re-create the problem. If it's fixed, then I would start adding a single piece of hardware at a time until I found the one that caused the problem. If none of that worked, I would most likely re-install the OS. I think I would also try resetting the optimized defaults in your BIOS and maybe even looking for an upgrade to your BIOS.
OK, here's how I ended up fixing the issue.
I used the comand stopx. Then when I got to just the command it gave me an option to fixx, so I did. And sure enough everything worked right then. I lost the configuration I had done in the Xconfig to make buttons 4 and 5 on my track ball act like a scroll wheel, and X config was back to default. I tried editing just that part again, and sure enough same problem. ( I just copied and pasted some code had I found on this forum).
Tomslick:I actually did have keytouch installed, but since I had gotten quicker results by simply changing the keyboard shortcuts in the XFCE Settings manager, I simply removed that program recently, though that was after I fixed it.
Now I'm back to trying to get those scroll buttons to work.
