John Maydew, thank you for reporting this and helping make Ubuntu
better. If you could also please test the latest upstream kernel
available that would be great. It will allow additional upstream
developers to examine the issue. Refer to
https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the
upstream kernel, please remove the 'needs-upstream-testing' tag. This
can be done by clicking on the yellow pencil icon next to the tag
located at the bottom of the bug description and deleting the 'needs-
upstream-testing' text. As well, please comment on which kernel version
specifically you tested.
If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.
If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.
If you are unable to test the mainline kernel, for example it will not
boot, please add the tag: 'kernel-unable-to-test-upstream', and comment
as to why specifically you were unable to test it.
Please let us know your results. Thanks in advance.
** Description changed:
NOTE: This came in via answers.launchpad.net for the cert programme. I
have played with the touch screen on a suitably configured 2120 and can
confirm that on older releases the touch screen DID work fine as a
single touch device (In my limited exposure to it). According to the
user who submitted this, he was fine with 11.10, but on upgrading to
12.04, the touch screen stopped working. Going back to 11.10 and it
works. Thus, this appears to be a regression in 12.04
The ubuntu certification for this netbook does not mention that the
touch-screen is unsupported in Ubuntu 12.04
Initially I had Ubuntu 11.10 installed on this netbook, the touch-screen
worked without issue. Upgrading to 12.04, however, has rendered the
touch-screen useless. The touch-screen itself is an Ideacom IDC 6651.
I've had no luck so far in locating proprietary drivers.
lsusb lists all my other devices correctly, apart from the touchscreen,
which is displayed as such:
Bus 004 Device 002: ID 1cb6:6651
xinput does not list it directly, but I believe it to be the Virtual
Core XTEST pointer, shown below.
Virtual core pointer id=2 [master pointer (3)]
↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
↳ SynPS/2 Synaptics TouchPad id=11 [slave pointer (2)]
Additionally, lshal shows the following information also related to the
touchscreen
