KDE doesn't log in after update

After one of updates I can't log in to KDE workspace, but I can log in to TWM and xterm.
This is a  pacman.log for that update. After updating, pacman said that I have some unused packages: cloog-ppl and elfutils, so I removed them. So how could I fix log in to KDE or at least easily downgrade all recently updated packages?

Re: KDE doesn't log in after update

At the login welcome screen (KDM), manually select the normal KDE session, and then try to login. (Do not select "Default".)

After you successfully login, you do not need to repeat this step anymore.

The only time you might have to do this again is if another update reintroduces this problem. I had to do this two times after updating KDE on my openSUSE system. No need to downgrade any packages. This is just an unusual glitch with KDE.

On second thought, I just re-read your post and it might not be the same problem. Did you manually select "KDE Plasma" (not Default) session?

Re: KDE doesn't log in after update

Yes, I've tried "KDE Plasma Workspace" and "KDE Plasma Workspace (failsafe session)" but I get only black screen for some seconds and then KDM login screen again.

Re: KDE doesn't log in after update

Anything unusual in ~/.xsession-errors or /var/log/Xorg.0.log?
And you could try removing/renaming your /var/tmp/kdecache-user directory.

Re: KDE doesn't log in after update

KDE fails to log in if you don't have enough remaining space in /var. Use df to check it

Re: KDE doesn't log in after update

After removing old packages from cache:

$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev             10M  132K  9.9M   2% /dev
/dev/sda8       6.9G  5.2G  1.4G  80% /
shm            1008M     0 1008M   0% /dev/shm
/dev/sda7        61M   15M   44M  25% /boot
/dev/sda9        51G   27G   22G  56% /home

I think there is enough space in /var to start KDE, but it doesn't works.
Also renaming /var/tmp/kdecache-myusername did not help.

Re: KDE doesn't log in after update

I've had a similar issue.
Is your Xorg fully upgraded? some applications seems to segfault with the newer glibc and an 'outdated' xorg-server.

Re: KDE doesn't log in after update

I have a problem with compatibility of my Nvidia proprietary driver and new xorg-server, so I stopped pacman from upgrading xorg-server, xorg-server-common and xf86-input-evdev.

Re: KDE doesn't log in after update

...at least we found the root cause.
Try pasting
ServerCmd=/usr/bin/X -br -ignoreABI into your kdmrc and use an older driver.
260.x works fine here.

reference here, other xorg/nvidia version, same workaround:

If the previous xorg-server (1.9) worked alright for you, you can try out the third-party Xorg repositories and downgrade; see this wiki page for more info.

Re: KDE doesn't log in after update

Setting ServerCmd=/usr/bin/X -br -ignoreABI in /usr/share/config/kdm/kdmrc and reinstalling my NVIDIA-x86-260.19.44 driver did not help.

Re: KDE doesn't log in after update

So downgrading xorg is your last hope; i did it like ANOKNUSA suggested.

Re: KDE doesn't log in after update

I need to use ATI Catalyst Xorg repository although I have a Nvidia card? Or I must to find absolutely any third-party Xorg repository? Beforehand sorry for my stupidity.

Re: KDE doesn't log in after update

I'm on nvidia too; even if that repository was born for ati users, it just provides "outdated" xorg packages, you can use it.

Re: KDE doesn't log in after update

I've disabled [extra] repository to deny official Arch xorg-server package installation and installed xorg-server and xorg-server-common from Catalyst repository, but I get nothing.

Re: KDE doesn't log in after update

no need to disable extra and manually install packages, just put:

[xorg19]
Server = http://catalyst.apocalypsus.net/repo/xorg19/i686

before any other repository in pacman.conf, then do pacman -Suy

Re: KDE doesn't log in after update

Ok, I installed xorg exactly from that catalyst repository and it behaves the same way as xorg from arch's extra. It's a pity, Arch is the most handy distribution that I used. Now I'm going to switch to Debian.

Re: KDE doesn't log in after update

did you downgraded nvidia and nvidia-utils to 260.19.44, right?

Re: KDE doesn't log in after update

I reinstalled my Nvidia 260.19.44 proprietary driver after that.

Re: KDE doesn't log in after update

I think you've to downgrade kernel too (260.x nvidia module is built for kernels older than 2.6.38) or install 260.19.44 from aur by editing PKGBUILD.
