I'd be grateful for any suggestions on the following strange (to me) behaviour. I am running RH7.3, XFree 4.2.0, with an ATI Mach64 card with a visible 1Mb of onboard RAM and a Sun0587 monitor. I boot into text mode (init 3) and run Xconfigurator, selecting all the defaults/probed values, and a resolution that is known to work (800x600, 16-bit). I can see the 'can you see this message?', and allow it to write the XF86Config-4 files. Then I 'startx', and all appears fine as Gnome appears. I save the /var/adm/XFree86.9.log file (calling it /var/adm/XFree86.9.log.successful) and delete the original. Then I run Xconfigurator again (from a terminal window in Gnome), again selecting exactly the same values. This time, however, instead of the 'can you see this message?' I get the grey screen of doom, and have to Ctrl-Alt-Backspace to get back to Gnome. /However/ it *has* successfully written the XF86Config-4 file. I save the /var/adm/XFree86.{0,9}.log files as .unsuccessful. The differences between XFree86.9.log.successful and .unsuccessful are: ("<" indicating the earlier, successful attempt from text mode, ">" the later, unsuccessful attempt from Gnome. < (==) Log file: "/var/log/XFree86.9.log", Time: Tue Jul 16 10:04:44 2002 --- > (==) Log file: "/var/log/XFree86.9.log", Time: Tue Jul 16 10:06:09 2002 29c29 < (--) using VT number 7 --- > (--) using VT number 8 53c53 < (II) PCI: stages = 0x03, oldVal1 = 0x8000003c, mode1Res1 = 0x80000000 --- > (II) PCI: stages = 0x03, oldVal1 = 0x00000000, mode1Res1 = 0x80000000 515a516 > AUDIT: Tue Jul 16 10:06:12 2002: 1522 X: client 1 rejected from local host At the end of the XFree86.0.log.unsuccessful file are the lines: AUDIT: Tue Jul 16 10:05:30 2002: 1295 X: client 6 rejected from local host (WW) Open APM failed (/dev/apm_bios) (No such device) (But I believe this is just a power manager thing and nothing to do with graphics?) So I start again, booting into text mode, and this time repeat the experiment but this time instead of starting X with 'startx', I go for the brute force 'xinit' (with no arguments). This time, Xconfigurator completes the second time just fine, and I see the 'Can you see this message?' screen. I'd be grateful for any suggestions on what I've missed - something obvious I imagine! And where else I might look for logged clues, since the XF logs don't seem particularly vocal. thanks in advance, Richard.
