Since I don’t know how to post outputs here because I can’t get into a DE nor i have the internet to upload somehow (my wifi drivers seem to have stopped working and I got no ethernet and tethered doesn’t work either) I’m gonna have to do this bit by bit.
To make this short, today I installed around 200MB of updates, so there probably were some new linux-headers and linux kernel versions. I restarted and then it was stuck in a loop at the login screen, I wasn’t able to get into TTY for some reason. I googled a bit and ran into someone saying he booted from installation media and did pacman -U to install an older version of headers and kernel. So I did that but I forgot to do umount /dev/sdb2 and it looks like it left unmounted. Then when I booted into the OS I got the black screen and the cursor. That’s when TTY started to work but Xorg and KDE wouldn’t run. Starting KDE using startkde gives me:
$DISPLAY is not set or cannot connect to the X server
and starting Xorg with startx gives me something like this:
[KMS] drm report modesetting isn't supported. Fatal server error: (EE) Cannot run in framebuffer mode. Please specify busIDs for all framebuffer devices. (EE) Please consult the x.org foundation support. (EE) Server terminated with error (1). Closing log file xinit: giving up xinit: unable to connect to X server: connection refused xinit: server error Xorg.0.log is a long one but this might be interesting where it says: FBDEV(3): using default device Screen 0 deleted because of no matching config section. UnloadModule: "radeon" Screen 0 deleted because of no matching config section. UnloadModule: "modesetting" Screen 0 deleted because of no matching config section. UnloadModule: "fbdev" UnloadSubModule: "fbdevhw"
As a failsafe, is there a way I could backup my system via this TTY to an external hard drive?
Helping me solve this will probably be a hassle so I appreciate anyone trying to help me (getting to my files is my primary goal so if I can copy them I can simply re-install the system).
My arch installation was installed using antergos, KDE , 4.10.11-1, xorg version: 1.19.3, lightdm.
If this question isn’t suitable in this section of the forum please move it. Thanks
