Hi folks,
i just got my brand new Lenovo X1 Carbon and trying to get Gentoo
running on it.
Beside some really big issues (HiDPI display, 2048x1152 resolution on a
14" display really sucks on linux, xrandr scaling is horrible, no
scaling is damn too small to read, missing touch support in most
applications, ...) I have a big problem with my kernel:
It doesn't come back from standby.
After closing the lid, the standby LED starts breathing, opening the lid
doesn't change anything, even pressing the power button does not wake up
the system. The only option is to reset the system by holding down the
power button. Journalctl doesn't say anything except of "System reboot"
after the Standby message:
ralf@omega:~$ sudo journalctl | grep -i "lid closed" -A
10
130
Aug 23 19:12:20 omega systemd-logind[2075]: Lid closed.
Aug 23 19:12:20 omega systemd-logind[2075]: Suspending...
Aug 23 19:12:20 omega systemd[1]: Reached target Sleep.
Aug 23 19:12:20 omega systemd[1]: Starting Suspend...
Aug 23 19:12:20 omega systemd-sleep[2175]: Suspending system...
-- Reboot --
......
So I tried installing Arch linux (same kernel version, 4.1.6). Arch
wakes up without any problems. As a try and quick fixI copied the Arch
Kernel+Modules to my Gentoo system and it works fine, which means to me
that I probably have a misconfigured kernel.
But that's not the Gentoo way, I'd like to compile the kernel on my own.
Does anyone know what I might be missing in my kernel config?
Or does anyone also have a X1 Carbon 3rd generation and would like to
share the .config with me?
Anything helps!
Cheers
Ralf
