[SOLVED] New install on Lenovo S540 won't boot to graphical login

mcloaked · 2014-03-13 22:21:40

I have a Lenovo Thinkpad S540 on which I have just installed arch as dual boot - it boots to Windows 8.1 and also successfully boots Arch linux to a console screen with the multi-user.target booting from rEFInd just fine. However with KDE packages installed it will not boot to a graphical login kdm greeter, and enabling the kdm service with

systemctl enable kdm

if I then reboot, the boot process starts fine ( the rEFInd boot manager graphical screen starts just fine ) but it does not give a graphical kdm greeter but instead a blank screen from which I can't switch to a text console using ctrl-alt-Fx

However if I boot to a text console and then login as user, then su - to root and issue the command

systemctl start kdm

then the kdm greeter is displayed normally and I can login to KDE without any problem. So the graphical login screen works if I start the kdm service when already logged in to a text console but not direct from the boot, which is a puzzle.

This system has hybrid graphics with Intel/ATI cards, and the system has an i7 processor

In the journalctl log there is the following but I don't know how to interpret this and don't know if this is the root cause of the problem with graphics (the lines are terminated at the console right hand side):

My refind_linux.conf file contains the boot lines as:

"Boot with defaults" "root=PARTUUID=xxxxxxxxxxxxxxxxxxxx ro"
"Boot to console" "root=PARTUUID=xxxxxxxxxxxxxxxxxxxx ro rootfstype=ext4 systemd.unit=multi-user.target"

where the PARTUUID value has been changed to xxxxxxxxxxxxxxxxxxxx for security.

If anyone can point me to a source for what to configure to get the basic graphical login working (and also how to get switching VT working too), then I will be grateful, as I have been unable to dig up a solution in the standard sources or by googling.

Thanks in advance.

Some progress today - adding two items to the MODULES section of /etc/mkinitcpio.conf as

MODULES="radeon i915"

At least does give me a graphical login now.

However I still can't switch to a text console using ctrl-alt-F1 etc, so I need to fathom out why the keyboard special keys don't work!

There is clearly still a lot of work happening in the kernel development world concerning hybrid graphics for Intel/ATI discrete/integrated switching which I need to fathom out, but certainly I don't have a directory called /sys/kernel/debug/vgaswitcheroo/

Edit: After simply "fiddling" and trial and error I found that there is a way to get the F keys working - which is quite bizzare. On the S540 keyboard there is the Fn key at bottom left, and by pressing that key at the same time as the Esc key (which is also marked FnLk) the green led on the Fn key lights up. Once that has been done then ctrl-alt-F2 will take me to VT number 2, and ctrl-alt-F7 will take me back to the graphical screen again. Quite bizzarre but it works!

I am closing this thread as the main problems are resolved.
