Had good times with KaOS until I just updated my system and everything suddenly stopped working. System comes up until a black screen with blinking cursor on top left! No login window! Nothing at all.

/var/log/kdm.log:

Loading extension GLX

Fatal server error:

Please help. I'm currently posting from a Debian installation. I cannot use my KaOS anymore :(

When did you do the update? Is it possible that you updated on a unsynced mirror? Octopi automatically checks for that on start-up, you can run "mirror-check" or use the mirror-check app, if you just use pacman to update.

But that doesn't help now......

You state you get to a black screen, blinking cursor, so I presume the system still loads (goes passed grub, loading kernel and systemd), bit can't start X.

Try to go to tty1 on that black screen by using "Ctrl-Alt-F1" keys.

If that gets you to a prompt, login as regular user. Run mirror-check. If the mirror is synced, update again (easiest to do all this with a wired network, to set up wifi in tty1 is bit more involved):

sudo pacman -Syu

If new updates come, then try starting KDE again by running:

startx

If it wasn't an incomplete update that broke X, then I'll need to get info on what settings you changed, that caused these conflicts, and/or list any package you installed not from the KaOS repos.

I have the same problem, it is related to the package xf86-video-intel-2.99.911-3

Just press Ctrl+Alt+f1 and install the previous version:

sudo pacman -U /var/cache/pacman/pkg/xf86-video-intel-2.99.911-2-x86_64.pkg.tar.xz

If the new intel package is the issue then no need to downgrade. It is only a change for the default backend, glamor, follow the instructions in your pacman.log to switch back to sna.

I'll post the instructions once I'm back at a PC.

Switch was done bc some newer hardware had issues with sna, but seems a rebuild will be needed to support older hardware.

EDIT:

These are the instructions you received during the update (you can look them back up in your /var/log/pacman.log):

post_install() {

echo "sna, uxa and glamor acceleration methods are supported"

echo "With glamor set as default"

echo "Use either sna or uxa method if you run into trouble with glamor."

echo "Try by creating /etc/X11/xorg.conf.d/20-intel.conf "

echo "Section "Device" "

echo " Identifier "Intel Graphics" "

echo " Driver "intel" "

echo " Option "AccelMethod" "sna" "

echo "EndSection "

}

Thank you demm! I'm in KaOS now!

Booted into my old installation (I have two root partitions each 15GB and I always keep the old one).

Edited etc/X11/xorg.conf.d/20-intel.conf of the KaOS root partition as below:

Section "Device"

Identifier "Intel Graphics"

Driver "intel"

Option "AccelMethod" "sna"

EndSection

rebooted and it worked :)

pacman -Syu would have fixed it too :)

The change to glamor as default is reversed, new xf86-video-intel package is back to sna as default.
