[SOLVED] X issues since 3.14

root · 2014-04-18 21:52:25

Since the update to 3,14 (and subsequent builds including 3.14.1-1) I have experienced issues with X on my T23.

When my display manager is supposed to appear (I am using SLiM) the screen enters a continued loop with the screen falling back to the virtual console after each (failed) attempt to load the display manager.

If I load the system in multi-user mode and try to start X with startx I end up with a black screen. I am nevertheless able to switch to tty1 and stop the server which stops without errors.

When checking Xorg.0.log for what is logged during the loop the logging always stops at this point,

[ 71.998] (II) LoadModule: "ddc"
 [ 71.998] (II) Module "ddc" already built-in

I must note though that I am running a locally build xorg-server package (see here for more details).

In order to see if that could have led to the problem I updated to the current xorg-server package and switched to the vesa driver (yes, savage driver is uninstalled; I do not use the latest as its performance together with xorg without XAA support is pretty sluggish on this laptop).

When using the vesa driver the endless loop does not happen but after not succeeding in loading display manager the screen stays at the virtual console. The log from X features the following errors,

[ 30.864] (EE)

 [ 30.869] (EE) 
 [ 32.832] (EE) Server terminated with error (1). Closing log file.

When searching for this 'Bus error' I came across this forum thread though if it were a problem/bug with X I presume it wouldn't load either with the LTS kernel which it does, would it?

Finally, if I too enter the system in multi-user with the vesa driver and run startx the same thing as with the savage driver happens, a black screen but I am able to switch to tty1 and stop the server which closes with no errors.

Seems latest kernel build (3.14.2-1) fixes this issue. Marking as solved.

Arch Linux
