What video card do you have and what drivers? |
12 |
|
13 |
I've had similar problems (not with this graphical live CD, since I |
14 |
installed Gentoo before it existed, but with X applications and X |
15 |
itself), because I have an ATI card. ATI cards do do that (just shut |
16 |
down the monitor) if 1) using the wrong drivers ("radeon" when card |
17 |
model is one above the 9(2/5?)50 (sorry, can't remember which model is |
18 |
the stopper for the Open Source drivers), and/or 2) DGA is enabled for |
19 |
the fglrx drivers (this will do exactly what you described; it has many |
20 |
times for me, and it is just one of the many PITAs with the fglrx drivers). |
21 |
|
22 |
The thing is-- in theory, I have no evidence to support this-- that |
23 |
GNOME (I am a GNOME user as opposed to a KDE user, though I don't use |
24 |
either of those DE's regularly or "first" during a new install due to |
25 |
their size) appears to require 3D support be working in order to load |
26 |
properly. Or at least, the hardware acceleration must be working if |
27 |
you're using drivers that supposedly support said acceleration. As I |
28 |
said, I have no evidence for this /per se/; it's just my theory based on |
29 |
experience. If you're using the 'vesa' drivers (which don't support 3D), |
30 |
I betcha GNOME will load fine (at least it always does for me), but as |
31 |
soon as you load drivers in your X config that are supposed to support |
32 |
hardware acceleration/OpenGL/3D, GNOME will break if that support is |
33 |
broken (even though, afaik, no basic operation of GNOME actually uses |
34 |
3D-- that's why this is a "theory" and seemingly rather a crackpot one, |
35 |
but it's the only theory that fits my experience). |
36 |
|
37 |
So I would suggest first changing your xorg.conf to load the vesa |
38 |
drivers, which should load (that's what they're for, default drivers |
39 |
that should always be able to load and display), then editing your |
40 |
xorg.conf to resolve the "obvious" problem that it must have. Some |
41 |
option or driver causes your video card to stop sending a signal. I know |
42 |
that >=9600 ATI cards do this when DGA is enabled on the fglrx drivers, |
43 |
and also that >=9(2/5?)50 cards do strange things when using the |
44 |
"radeon" drivers which don't support these models for hardware |
45 |
acceleration, as opposed to the "fglrx" drivers which do-- but the |
46 |
LiveCDs will tend to (in my experience) recognize my 9800SE as an ATI |
47 |
card and load the "radeon" drivers incorrectly because the "fglrx" |
48 |
drivers that the card needs are not open source... and the "radeon" |
49 |
drivers don't actually work properly for my card. But you may have a |
50 |
different brand of card, or it could be a different option causing this. |
51 |
|
52 |
You might want to copy /var/log/Xorg.0.log to a backup location before |
53 |
you try to start X with the vesa drivers (since the vesa drivers should |
54 |
load correctly, it will overwrite the log with the errors and you need |
55 |
to know what they are, so backup the log with the errors first, is that |
56 |
I'm suggesting). |
57 |
|
58 |
But the first thing we'd have to know is what is the video card, and |
59 |
what are the loaded drivers; then we can work on things like what video |
60 |
options you set in the kernel, and what you've got for modelines and the |
61 |
like in xorg.conf (though I doubt that the issue is modelines, since |
62 |
that just knocks you out fo X completely with a "no screens found" |
63 |
error, not kills your signal between video card and monitor while |
64 |
leaving X actually running). |
65 |
|
66 |
Anyway, hope this helps. |
