Some observations... |
16 |
|
17 |
1) Since you get the login screen, X has to be working. Presumably, |
18 |
that's with full root permissions. |
19 |
|
20 |
2) When you try to login, screen blanks and eventually returns to the ?DM |
21 |
login screen. Of course, in the process of logging in as your user and |
22 |
getting a kde or twm session, you'll switch to user privs for some |
23 |
things. That this doesn't work but the login screen as root does, hints |
24 |
at a permission issue, or an issue setting up the user "magic cookies" |
25 |
that allow an ordinary user to access the xorg server running as root. |
26 |
|
27 |
3) That begs the question [1], what happens if you create a fresh user and |
28 |
try to login as them, and/or if you try logging in as root? (Yes, I don't |
29 |
recommend it for normal usage either, but for testing... disconnect from |
30 |
the net if you're paranoid, backup your /root so you can restore it to pre- |
31 |
X-login condition afterward, and try the root thing.) If a new/clean user |
32 |
works, then you know it's something in the user config. If it doesn't but |
33 |
root works, you know it's a permissions issue of some sort. |
34 |
|
35 |
4) Due to ?DM breaking on me years ago on Mandrake, I quit using ?DM |
36 |
graphical logins then, and have never gone back, choosing instead to login |
37 |
at the text console and startx as my preferred user. You mention nothing |
38 |
about even trying that. Does /that/ work and you simply prefer the |
39 |
graphical login, does that not work either, or were you unaware of the |
40 |
option? |
41 |
|
42 |
Obviously if it works you have a workaround. At least that way you can |
43 |
run your graphical environment of choice, even if you don't like the login |
44 |
method. Plus, the results of this test should help someone a bit more |
45 |
skilled in ?DM technologies than I am (as I said I quit DMs long ago) |
46 |
figure out what's going on. |
