Hello all,

I'm the happy owner of a new X1 Carbon 7th gen (i7, WQHD Anti-glare, with NFC, no WWAN) and first thing I did was install Ubuntu. I've followed every tutorial I could find on how to configure bios and what to keep in mind when installing linux. After that successfully installed Ubuntu 18.04 and everything seems fine. However after some use I run into two problems on both 18.04 and 19.04 using BIOS version 1.14

Touchpad not working

The touchpad is not working about half of the times that I boot the system. I found a lot of "fixes" / "workarounds" but none of them work for me. I am also not able to fix it when it's not working unless by rebooting and hoping it starts.

xinput list:

⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ SYNA8005:00 06CB:CD8C Touchpad id=10 [slave pointer (2)] ⎜ ↳ TPPS/2 Elan TrackPoint id=12 [slave pointer (2)] ⎜ ↳ Designer Mouse id=14 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Sleep Button id=8 [slave keyboard (3)] ↳ Integrated Camera: Integrated C id=9 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)] ↳ ThinkPad Extra Buttons id=13 [slave keyboard (3)]

dmesg log full of:

i2c_designware i2c_designware.1: controller timed out

Deep sleep not stable

Deep sleep has not been working stable for me. Whenever I close the lid experience on of these three situations:

- It goes to sleep, power led starts blinking but after 10-15 seconds it powers back on, no weird statements in dmesg log

- It goes to sleep, power led starts blinking but after some time the device restarts itself and goes to ubuntu disk decryption screen and stays there (draining my battery)

- Screen goes black, power led stays lit, cannot do anything anymore except reboot

- On a very rare occasion deep sleep seems te be working

(Sleep mode is set to Linux in BIOS)

I really hope someone can help me with this as I'm very excited about the new X1 Carbon. It would be a bummer if i'd had to go back to Windows, since this is not workable.

Thanks
