After having been happy with several previous versions of the X200-series, I have now bought a Yoga260 notebook.

Unfortunately, I have not been able to get a stable installation of Linux Mint Sarah KDE. The culprit seems to be the trackpad/trackpoint hardware or driver. After some use, the mouse cursor consistently freezes indefinitely, with only a reboot helping. Also, mouse clicks go missing so that I regularly have to click several times.

In syslog, I find lots of messages like this:

psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6

psmouse serio1: elantech: PS/2 packet [
0x80, 0x26, 0xfa, 0x06, 0x10, 0x00 ]

I have updated the BIOS to the newest version (I thought it might be a firmware issue), but the situation remained.

This problem seems to be the same as described here: https://bugzilla.redhat.com/show_bug.cgi?id=1313939

I'd be interested if anybody has been able to install Linux without this problem. If yes, what distro/kernel/drivers have you used?

What also is a bit of a nuisance is that although I have disabled the trackpad in the BIOS setup (I only use the trackpoint) it still is active under Linux. I had to disable it by software (using synclient).

Hi - Here the Ubuntu certification page for the Yoga 260: https://certification.ubuntu.com/certif ... 512-20419/

I suggest That you contact "the Alternative" concerning your questions. They received test devices from us (not sure if the Yoga 260 was one of them). http://thealternative.ch/index.php

Best regards,
Simon

Regardless of this certification, these mouse problems occur both in kubuntu 14.04 and 16.10 (with kernel 4.8 ). To me this indicates that either the hardware versions differ, or that the system was not really tested for proper functioning), or that my notebook is broken, which I doubt.

Mouse clicks get lost and I have entries like this in syslog:
Code: Select all
Nov  1 20:51:40 Y260 kernel: [ 7966.993035] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6
Nov  1 20:51:40 Y260 kernel: [ 7967.000405] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6
Nov  1 20:51:40 Y260 kernel: [ 7967.000413] psmouse serio1: issuing reconnect request

From time to time the mouse freezes completely. The only way out I could find so far is to switch to a text console (e.g. CTRL-ALT-F1), log in, and issue
Code: Select all
sudo rmmod psmouse
sudo modprobe psmouse

and then switch back to the desktop (ALT-F7). The mouse then works again for a while (except for the glitches described above) until it freezes again.

This is very annoying. Again, I would welcome any feedback from other users that run Linux on the Yoga260.

Dear Pascal,

I'm not sure if there are currently users in the forum that use a Yoga 260 with Linux.

As I suggested: Contact "the Alternative" concerning your questions (they are part of VSETH) and they received devices from us for testing (as far as I know also a Yoga 260). That is easier then being annoyed and waiting for a reply in the forum.

Dear Simon,

I already did as you suggested. However, I also post here to document the issue. Here is a place where Neptun Customers likely will do a search.

Great! I'm sure they will have a solution for you and I'm thankful that you document the solution here in the forum.
