Random things to try while waiting for better ideas to try: |
40 |
|
41 |
startx -- -logverbose 10 |
42 |
|
43 |
In your .xinitrc try /etc/X11/Sessions/<kde-start-script> if kde |
44 |
supplies such a script. |
45 |
|
46 |
Have you tried using kdm instead of startx? (Even thinking about that |
47 |
raises my blood pressure :) |
48 |
|
49 |
Are you using anything from kde-plasma? (Just running 'eix plasma' |
50 |
makes my blood pressure even higher. The number of permutations |
51 |
involved makes me glad I use xfce4, which is already way too complex |
52 |
for my taste. How xfce4 behaves depends a lot on whether its |
53 |
compositing feature is on or off. Does kde allow you to tweak stuff |
54 |
like that? Of course it does, but not if Xorg dies before you can do |
55 |
the tweaking. (Reaching for blood-pressure pills now...) |
