Can't Boot After Upgrading To 2.6.31

**synace** · July 10th, 2009

i see that result when i was trying to get my touch/pen working on 9.04.

if i restore the original (fglrx) or failsafe (vesa) xorg.conf, i'm good to go.

- boot into recovery mode
- drop to a root shell w/ networking
- fix /etc/X11/xorg.conf (or copy /etc/X11/xorg.conf.failsafe to /etc/X11/xorg.conf)

i can boot normally again.

note, whenever this happens, i lose keyboard input too it seems.

Hi synace,

You don't need to do a kernel upgrade in Jaunty to get the stylus and pen working for your n-trig digitizer anymore. This link will take you to a xorg.conf and a link to Ayuthia's deb.s and instructions. See appenidix 2 at the bottom: http://ubuntuforums.org/showthread.php?t=996830

side note, to get rid of the old kernel (from a root recovery shell):

uninstall the extra kernel

dpkg --purge ...headers
dpkg --purge ...headers-generic
dpkg --purge ...image...

apt-get install --reinstall ...headers
apt-get install --reinstall ...headers-generic
apt-get install --reinstall ...image...

your current kernel's parts (headers, headers-generic & image)

you should be able to boot back to where your machine was before you added the extra kernel

checking it out.. i didn't upgrade, just wanted to get the stylus & right click working (right now the button is middle-click).

i'll try those patched kernel files.

edit:
i'm actually on 2.6.28-13.45, those are 2.6.28-13.44

i used the xorg.conf in the bzip package in his post.

got a warning about downgrading.. rebooting & trying

i ended up w/ the same thing seen on page 1 here.

trying xorg.conf adjustments. if that doesn't work, i'll reninstall .45.

that worked.. ok.. i'm on Ayuthia's patched kernel, but his xorg.conf doesn't work for me. fglrx does work for me.

touch 'IS' working (it's no-longer going to the top-left corner, X11 registers something). although, it's not responsive or accurate and sporadic. maybe have to adjust wacom sensitivity? if i use 3 fingers, it works, 1 finger, no go.

pen works still, though, button is still middle click.

my xorg.conf:

Hi synace,

Use the xorg.conf attached to the bottom of the HOW TO that appendix 2 is on, linked above.

Ayuthia says swiping a couple fingers across the screen gets touch back for him.

See, starting with about post #12, more info. here: http://ubuntuforums.org/showthread.php?t=1162477&page=2

using that one gives me a screen similar to post 1 in this thread, after which i have to shutdown (power button), boot into recovery, fix xorg.conf and start over.

Hi synace,

Looks like that's due to the way you have "fglrx" setup. Just swap the wacom entries for stylus and touch in the order they are in for the ones you have. Also include the wacom "ServerLayout" entries. Ayuthia mentioned he had to reinstall ATI proprietary after substituting in his patched kernel.
