Ubuntu on Eee PC T101MT

[mikshepard]

I have this working perfectly on Ubuntu, but now I am trying to get it working on debian squeeze. Everything works great but when I rotate the screen, the mouse does not follow. I'm guessing its a problem with the touchrotate script not rotating the screen input as well, like it does in Ubuntu. I'm not sure what the difference would be that would be causing this. I know this forum is mainly for Ubuntu but I would greatly appreciate any help or ideas, thanks!

I had the same problem but I was using "touchscreen toleft" etc. When I used

"touchrotate LVDS1 10 toleft" it seemed to work fine.


Here's my problem: I have two versions of kernal installed.

32-22 and 32-25

When I boot it in 32-22, the x display hangs and I can only hard reboot it. When I boot in 32-25, my X display works but touchscreen does not. I was trying a lot of things when trying to get touchscreen working but am not sure where I goofed up. Any help would be greatly appreciated.

Thanks

@jpfle:
Strange, maybe your model uses different signals for the buttons. Normally, eeepc_laptop should handle this button.

@toylas:
You need to reinstall the driver when you use a new kernel version. You probably have only installed it for 32-22?

[toylas]

Thanks for the reply Plippo! I just checked, I had the kernel version wrong in my last post (sorry about that). I have 32-25 and 35-22 installed. The touch worked fine in 35-22 when I upgraded everything and had the drivers installed.

Also when I try using the multitouch driver .deb files provided on the community documentation page, I get an error saying wrong architecture.

But now when I boot in 35-22, X freezes actually the input freezes completely. I mean I can't even go to the shell modes by pressing Ctrl+Alt+F2 etc. I tried booting in recovery mode and then failsafeX but even that does not work.

I have attached part of the failsafe X log file. It says segmentation fault just before the start of end process. I do not understand these messages enough to be able to make out the problem. Any help/pointers would be greatly appreciated.

Thanks

I tried that but still got the same result, the touchscreen mouse input doesn't rotate with the screen. Any other ideas on how to fix this? (Again this is on Debian squeeze). Thanks for any ideas!

Great thread. Took a couple of hours to go through it all. Everything works great.

I would like to add that DheathNone's suggestion:

The rotate button problem came back after upgrading to maveric and I can't apply the same fix just now. So, I think the easiest and least hackish way to do this is to put in
~/.Xmodmap:
------
keycode 160 = XF86RotateWindows
-------
(and then $ xmodmap ~/.Xmodmap)

This basically marks the key 160 (rotate button in eee T101MT) as a XF86RotateWindows which I think is not used any where with this. Now as the gnome-power-manager seem to search for the key button XF86ScreenSaver pressing it won't lock the screen any more.

Better ideas?

Works really great.

I still have to test and look into MyPaint issues.

[maxim_86ualb2]

I am having an issue with MyPaint where lines form between brush strokes, does anyone have a solution for this issue. I am using the latest version in the repo 0.8.2.


I must have missed the fix in this thread:

Works really great.

Actually this was not such a good idea in the end. After some upgrade the gnome seems to take that key and actually rotate the screen by its own means. This means the touchscreen does not rotate but the screen does!

Use instead:
keycode 160 = XF86[insert some clearly useless action(google something)]

I used XF86Eject, because it was useless for me and it was possible to actually change the shortcut for eject from keyboard shortcuts!

Dear all,

I've been trying to get kernel 35-22 working on my machine without any success. I posted the xorg log last time. I looked into it and found that the x server was crashing with a seg fault. The errors

I've tried reinstalling libc, evtouch drivers, liblpthrea etc but I still can't get X to work in kernel 35-22. Any ideas would be greatly appreciated.

Thanks.




P.S. :I also got into another trouble, which might not be relevant to this thread but I guess I'll share it. I was trying to boot Android with a USB stick on my T101 but somehow it gave me trouble. So I restarted the computer by Ctrl+Alt+Del but now I can not see the bios setup and boot menu screens. All I can do is to boot in Win7 by pressing enter and choosing the default boot option. Any ideas what could be wrong?

I also have some recent problems with updates and installation. The following message has been appearing for a while and I don't know how to get rid of it. Hope someone has a solution to this:

You have to configure "localepurge" with the command

dpkg-reconfigure localepurge

to make /usr/sbin/localepurge actually start to function.

Nothing to be done, exiting ...
