I chose between this machine, a Txxx and Dell. I went the easy route this time. Not much research, just needed a replacement. The rest is going to be about using the machine with GNU/Linux Ubuntu.
General and summary
Out of the box, I actually ran the Windows installer, used Windows for a few hours, getting Ubuntu Desktop 17.04 ISO and put it on a USB stick.
Rebooted, pressed enter to abort normal boot, selected USB device (it said
multicard reader), worked as expected from that point - except for the pointing device(s).
- All works out of the box (that I’ve tried), except for the trackpad - ie the touchpad and trackpoint (red dot thing between keys G, H and B). This device doesn’t show up under either fresh 16.04 LTS, nor 17.04.
- My best current setup uses linux boot parameter
i8042.reset i8042.nomux psmouse.proto=imps
Hardware Support and Features Tested
All of these are tested and works as expected:
- USB-C multi-adapter with HDMI
- USB-B ports
- built-in speakers, but position has changed so sound is muffled when laptop is put in your lap (as in laptop)
- webcam - takes 7 seconds to start though
Not yet tested:
- wan, gsm
- headphone jack
Added a line to
70-pointingstick.hwdb (after reading some thread on reddit, but it made no difference.
xinput still doesn’t list the device:
ceda@lx1carbon5:~$ xinput ⎡ 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)] ⎣ 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 id=9 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)] ↳ ThinkPad Extra Buttons id=12 [slave keyboard (3)]
Changed BIOS to:
- disable Security » Secure Boot » Secure Boot
- enable Security » Virtualization » Intel (R) Virtualization Technology
- enable Security » Virtualization » Intel (R) VT-d Feature
- enable Config » USB » Always on USB » Charge in Battery Mode
- disable Config » Beep and Alarm » Keyboard Beep
Three ideas where posted on Launchpad a long time ago.
modprobe psmouse resetafter=0 - just got worse.
GRUB_CMDLINE_LINUX_DEFAULT, and then running
update-grub2. Reboot. This made it a little better, ie it works more often but still completely unusable and unreliable.
b, then a)
xinput now shows the device as
PS/2 Generic Mouse.
c) Kernel boot argument
acpi_osi=Linux - no improvement over any of options above.
Another idea to try out was found on ubuntuforums.org:
i8042.reset i8042.nomux as boot parameters to Linux kernel. This had the best result, where the mouse was useable every 5-6 seconds, for a duration of less than a second.
Someone else had issues and tried different protocols:
modprobe psmouse proto=imps and the
imps protocol works for simple things, but scrolling seems to not be supported - or at least working - using this protocol.
apt install openssh-server
ssh -X 192.168.1.232 ‘x2x -east -to :0’
