I’ve loaded 11.3 & KDE 4.5 on my wife’s Acer Aspire One D255. Outside of wireless that didn’t work until I’d loaded the latest updates using Cat5, all is working great except that the touchpad is very super sensitive and that makes typing very problematic.
Note: Win7 device manager ID’s the touchpad as an “Elan PS/2 Port Smart-Pad”
Various posts seemed to indicate that this Elantech device might use the Synaptics drivers. I tried using gsynaptics to disable the touchpad so she could use a mouse, but the only result is an error message that says “GSynaptics couldn’t intialize. You have to set ‘SHMCongig’ ‘true’ in xorg.conf or XF86Config to use GSynaptics.” That message wasn’t useful, as neither file exists in 11.3
I then looked in KDE>System Settings and finally found the touchpad icon in the Lost and Found section (?). When I clicked on it the “Touchpad settings and management” window opened and contained only the error message “Warning. Touchpad configuration is not supported on this system. The Synaptics driver is either not loaded or is too old…”
Neither lspci or lsusb reveal any mention of any pointing device of any sort.
Xorg.0.conf doesn’t mention any touchpad but does contain numerous lines beginning with ImPS2 Logitech Wheel Mouse despite the fact that there’s no mouse connected, and there’s no external PS2 port to connect one to.
You have to check your X logs to find out what is really getting recognized/loaded.
cat /var/log/Xorg.0.log
Once you identified that, look at its configuration in /etc/X11/xorg.conf.d/ directory. You may tweak that configuration once you have identified that.
I finally managed to find an Ubuntu bug report on a similar problem that suggested a newer Kernel would solve this issue. I managed to download and compile 2.6.35.7-0.3
That change did solve this problem beautifully, better than I’d hoped in fact as I now have the option to “automatically switch off touchpad, if a mouse is plugged in” and/or “Automatically switch off touchpad on keyboard activity”.
So far so good, BUT now the PC no longer has wireless>:). I’ll be starting another thread regarding that issue shortly.
Can you post the full Xorg.0.log? (You may skip the initial portions that talks about the video driver etc. Typically, search for “input device” and copy from that line onwards).
[Edited: Forget this as you have solved the problem]
Sorry I haven’t been participating lately, I’m still on the road and won’t have time to get back to this 'til next week when I’ll finally be back home. For now I needed a quick fix and reloaded 11.3 from live CD (via thumb drive). That gives us back our wireless (see here for that story). We’re living with the “plain vanilla” load and the hypersenstive touchpad until we can give our full attention to coming up with a more satisfactory resolution
I finally got both the touchpad issues and the wireless going by using 11.3 and the 2.6.36 kernel to get the touchpad resolved then repaired the wireless issues that resulted by using the solution I described HERE.
For what it’s worth: I’m not crazy about the new kernel, as the machine isn’t completely stable, but overall it’s perfectly usable for the limited purposes that a netbook is good for. That’s a heck of a lot better than we started with.
