Hello there,

I along with many have been enjoying Karmic since its release. However, I am having a few issues.

Number one right now, is the keyboard. At the moment, when I boot into 9.10 Ubuntu Desktop and hit alt-tab, I am unable to switch between applications. This behaviour isn't occuring in Windows, as I am able to switch using the same alt and tab with no problems.

It may be hairy debugging the problem, because I have an Asus 1005ha and its been having keyboard issues (in Windows also). The one issue I am seeing repeated in Windows, is that after the machine is on for some time, the keyboard shuts down. The system doesn't respond to keypresses unless I insert a usb keyboard or reboot. (This problem is rumoured to be due to heat. Maybe a fan control script would prevent this.)

For starters, can someone help me with my alt-tab problem? I don't know where to start, but here is a snip of my xev output. When I depress right alt and release, I get:

KeyPress event, serial 36, synthetic NO, window 0x4000001,
root 0xfa, subw 0x0, time 241894, (164,13), root:(907,175),
state 0x0, keycode 108 (keysym 0xfe03, ISO_Level3_Shift), same_screen YES,
XKeysymToKeycode returns keycode: 92
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False

KeyRelease event, serial 36, synthetic NO, window 0x4000001,
root 0xfa, subw 0x0, time 242285, (164,13), root:(907,175),
state 0x80, keycode 108 (keysym 0xfe03, ISO_Level3_Shift), same_screen YES,
XKeysymToKeycode returns keycode: 92
XLookupString gives 0 bytes:
XFilterEvent returns: False

The interesting part is that in Ubuntu, when I hit right alt-tab, a tab character is produced for program input. That is, a tab is entered in gedit, and Bash interprets it as a tab also, offering completion options. I have only used UNR on this computer up till now. The present behaviour is new, after a fresh install of Ubuntu Desktop from the alternate install cd on usb. Maybe I'll try and duplicate the problem using the standard desktop installer.

Ok, it seems the problem doesn't occur with the desktop system installed from the livecd. The problem only occurs when installing from the alternate iso. I should also mention I had used the ubuntu usb startup disk creation utility to use the installer from usb.

It is a bit perplexing, as I had wanted to start from a command line system. My 1005ha doesn't have an optical drive, and the alternate cd doesn't recognize my usb dvd rom drive. It seems it is still a bit fudgy to install such a system on my hardware.

My issues from this point are pretty much resolved (grumble, grumble). But my conscience makes me wonder if it is better to file a bug about the problem. (I wouldn't even know what to file it against at this point.) Maybe in a week or two after I fix my desktop I can set up a couple of vm's and compare the filesystems/files.

Do you think it's related with your Laptop?
Same problem with DELL XPS M1330.

Installed from the live CD, same problem!!!
