I wouldn't bet on that... just because the liveCD boots and loads what seems to be X doesn't mean that the settings that you ultimately wound up with for X are sufficient and correct to load a full desktop environment. The installer has limited needs (so really doesn't need more than the failsafe vesa drivers), and a full DE has many more requirements. Also, the "x####" cards are particularly problematic in terms of X drivers at this time. > maybe the screen don't support the resolution set by default (1024 x > 768 was the resolution the live cd set by default on my pc and it > worked great) Well, you might have a point there (no way to know without more detail), but again, the symptoms of that don't necessarily fit the conditions you're experiencing. It's true that most modern monitors will shut off to save themselves if told to operate in parameters out of their range (for example if I told my monitor to run at 1600x1200 when it only does 1280x1024 with difficulty). But if the resolution is set by default, then auto detection should have told the x setup what the correct parameters for your monitor are and the default setting should be within the correct range. Did you change something, and now the default resolution is *not* 1024x768 (which ought to work for almost any monitor, certainly a current flatpanel)? And secondly, as I said, the usual result of X asking a monitor to display at a higher resolution than the monitor says it can do is *not* signal loss-- it's either a "no screens found" error (if the higher resolution is the only setting available), or display at a much lower resolution than you asked for (if lower settings are available, X will try them all until it finds one that fit within the monitor's stated parameters of vsync and hres). Signal loss, in my experience (which is admittedly limited, but since most people never experience signal loss at all-- which is as it should be-- even limited experience seems valuable), indicates a very specific range of conditions that might cause it, and they are almost all related to the video card and its drivers and settings, rather than anything to do with the monitor itself (after all, what do you think sends or doesn't send a signal to the monitor :-) ?). What does your Xorg log say (/var/log/Xorg.0.log), and what are your settings for the monitor and video device in /etc/X11/xorg.conf? Also, bizarre as it sounds. is this a new card, or have you been swapping things around inside your case before this install? You might check the seating and connections of the card. Although your situation is slightly different from mne-- you have a flat panel which presumably uses the DVI connector natively, whereas I have a CRT and must use the included DVI-to-VGA converter plug-- I have noticed that several times after modifying something internal to the box itself (whether related to the video card or not), I often had to open the box a second time and reseat the card and/or the monitor connection, which resolved errors I would suddenly be getting for "no reason". So you might want to check that as well, though perhaps the connectors have been redesigned since my 9800SE came out (and so are not loosened at the slightest little thing).
