Thread: GDM+Virtual Desktop+9.04->9.10

-

hello,

have problem gdm. on ubuntu 9.04 everithing working great, after upgrading 9.10 gdm login screen have size of virtual desktop, , can't see whole login box, have scroll horizontally screen using mouse see whole box.

here xorg.conf:
code:
section "serverlayout"     identifier     "layout"     screen      0  "lcd_screen" 0 0     screen      1  "tv_screen" endsection  section "module"     load           "glx" endsection  section "serverflags"     option         "xinerama" "off"     option         "clone" "off" endsection  section "monitor"     identifier     "lcd"     modelname      "gateway hd1900" endsection  section "monitor"     identifier     "tv"     vendorname     "samsung le32a551" endsection  section "device"     identifier     "0 nvidia geforce 8600 gt"     driver         "nvidia"     vendorname     "nvidia corporation"     boardname      "geforce 8600 gt"     busid          "pci:1:0:0"     screen          0     option "twinview" "true" endsection  section "device"     identifier     "1 nvidia geforce 8600 gt"     driver         "nvidia"     vendorname     "nvidia corporation"     boardname      "geforce 8600 gt"     busid          "pci:1:0:0"     screen          1     option "twinview" "true" endsection  section "screen"     identifier     "lcd_screen"     device         "0 nvidia geforce 8600 gt"     monitor        "lcd"     defaultdepth    24     option         "twinviewxineramainfoorder" "dfp-0"     option "metamodes" "crt: null, dfp: 1440x900 +0+0; crt: 1360x768_60_0 +1440+0, dfp: 1440x900 +0+0"     option "dynamictwinview" "true"     subsection     "display"         depth       24         modes       "1440x900"     endsubsection endsection  section "screen"     identifier     "tv_screen"     device         "1 nvidia geforce 8600 gt"     monitor        "tv"     defaultdepth    24     option "dynamictwinview" "true"     subsection     "display"         depth       24         modes       "1360x768_60_0"     endsubsection endsection
on xorg.conf have 2 screens, 1 monitor, other 1 tv. video card nvidia geforce 8600 gt. i'm using xrandr switch between displays:
xrandr -s 0 activate lcd
xrandr -s 1 activate lcd main desktop , tv on right of desktop, example can move mplayer window tv

interesting thing after log in system it's normal - lcd turned on , tv turned off. problem gdm - lcd turned on, has resolution 1440x900 virtual desktop on makes virtual resolution 2800x900 - seems when gdm starting it's trying show whole virtual screen on lcd, while after log in xorg showing 1440x900 of whole 2800x900 virtual screen , rest destined handled tv...


edit: i've manage solve problem, if can call solution, solution:
because gdm chooses first of defined metamode, instead of writing:
code:
option "metamodes" "crt: null, dfp: 1440x900 +0+0; crt: 1360x768_60_0 +1440+0, dfp: 1440x90
i'm writing:
code:
option "metamodes" "crt: 1360x768_60_0 +1440+0, dfp: 1440x900 +0+0; crt: null, dfp: 1440x900 +0+0;"
in way virtaul screen resolution 2800x900 before, tv on when gdm starts, see log in box on center of lcd screen, after log in tv becomes off, , can turn on or off using xrandr.
