penmountlpc crashing after upgrade

raygeeknyc · December 07, 2009, 04:58:40 AM

Not leaving well enough alone...
I had my a33i working. the pointer and the touchscreen. I needed to calibrate, but all seemed well.

I used aptitude to update and then upgrade. Among other things, the kernel was upgraded to 2.6.24.25 and xorg is now at xorg-server 1.4.0.90.

X crashed and came up with the lores, "configure me" session.
I installed my old xorg.conf one piece at a time and found that the penmountlpc driver is crashing X when included in xorg.conf.

I rebuilt the plpevtch driver in the new kernel using flybuntu-development-20080922.tgz but that didn't help
I then tried building and installing it from the xf86-input-plpevtch-0.4.0.tar.gz archive which was newer than the plpevtch included in the flybuntu-development archive. This didn't help.

FWIW - What seems odd to me is that even when I do not include the touchscreen device (using penmountlpc) in xorg.conf, the X pointer responds to touchscreen events.

I've attached the Xorg.0.log file from the crash which includes the stacktrace.

Any and all help is welcome.

hi,
delete the file /usr/lib/xorg/modules/input/plpevtch_drv.so and compile plpevtch 0.4.0 again.

howto compile and install:

Code Select


./configure --prefix=/usr && make
sudo make install

Hi Elmar
Already had, did again. Same result.

Elmar · December 07, 2009, 16:52:14 PM

did you recompile the penmountlpc module too?

raygeeknyc · December 07, 2009, 17:42:42 PM

yes, just removed it and recompiled to be sure. The size of penmountlpc.ko did not change, and it does differ from the one under the old kernel.

Elmar · December 07, 2009, 21:02:28 PM

maybe the eventdevice number has been changed
check it with

Code Select


dmesg|grep pen

Here's what I've got... (FWIW - upgraded to kernel 2.6.24-26 and rebuilt, same results
