NB30 11.04 touchscreen

Postby jlparsons » 05/05/2011, 22:59

So I had got everything working on my NB30 under 10.10 and I went and updated to 11.04... daft I know.

Everything works with the tried and tested fixes on here except the touchscreen which works on startup but fails after suspnding and resuming. Anyone have any ideas how to fix this?

Thanks folks!

I had this problem too, and fixed it.

I actually had the same issue (working fine until sleep/wake) with my wireless. I just applied the solution I found for that to the touchscreen and it worked.

Previously I'd been manually unloading and reloading the wifi module with these two commands after every resume from sleep:

Code: Select all

sudo rmmod r8192e_pci; sudo modprobe r8192e_pci


Which worked, but was a bit cumbersome. This forum post pointed to a website that told me how to get the computer to do this automatically:

http://www.voria.org/forum/viewtopic.php?f=3&t=782&start=15#p5165

you need to create a file called unloadmodules, in the directory /etc/pm/config.d/ and put a line in it like SUSPEND_MODULES=”r8192e_pci hid_egalax” with a space separated list of all the modules you want given a kick on resume (you can use lsmod to list the ones active on your system).

The original post tells you to use vi, which is what I used, but it can be a bit scary so this line should create/overwrite (so check there's nothing there first) the file with the single line in it:

Code: Select all

sudo echo 'SUSPEND_MODULES="hid_egalax"' > /etc/pm/config.d/unloadmodules


Note that there's a closing double quote and then a single closing quote before the > character. A reboot and that should be you.
