Gnome low screen resolution (just 640x480)

[Rubin-Rah]

I'm trying and trying and still hoping that a wise guy can help me:

so here so additional information to this problem:



I added this line to the xorg.conf:

ModeLine "1600x1200 at 75HZ" 162.00 1600 1656 1848 2160 1200 1200 1203
1250 

and changed in the subSections "Display" Mode to "1600x1200" "1024x768"
"1600x1200 at 75HZ".

I deleted the lines VendorName and ModelName.



I tried "radeon" driver instead of "ati" - same resolution (640x480)



would like to post some parts of my /var/log/Xorg.0.log:



It seems to recognise the first monitor!? (The second isnt connected to
the notebook)


Code:
--------------------
    

  (II)RADEON(0): Primary:

  Monitor   -- LVDS

  Connector -- DVI-D

  DAC Type  -- TVDAC/ExtDAC

  TMDS Type -- Internal

  DDC Type  -- DVI_DDC

  (II) RADEON(0): Secondary:

  Monitor   -- CRT

  Connector -- VGA

  DAC Type  -- Primary

  TMDS Type -- NONE

  DDC Type  -- VGA_DDC

  (II) RADEON(0): PLL parameters: rf=2700 rd=12 min=12000 max=35000; xclk=18300

  (WW) RADEON(0): Failed to detect secondary monitor DDC, default HSync and VRefresh used

  (==) RADEON(0): Using gamma correction (1.0, 1.0, 1.0)

  (II) RADEON(0): Validating modes on Primary head ---------

  (II) RADEON(0): Panel ID string: 1600x1200

  (II) RADEON(0): Panel Size from BIOS: 1600x1200

  (II) RADEON(0): BIOS provided dividers will be used.

  (II) RADEON(0): Total number of valid DDC mode(s) found: 0

  (II) RADEON(0): Valid mode using on-chip RMX: 1600x1200

  (II) RADEON(0): Valid mode using on-chip RMX: 1024x768

  (II) RADEON(0): Valid mode using on-chip RMX: 1600x1200 at 75HZ

  (II) RADEON(0): Total number of valid FP mode(s) found: 3

  (II) RADEON(0): Validating CRTC2 modes for MergedFB ------------

  (II) RADEON(0): CRT2 Monitor: Using hsync range of 28.00-33.00 kHz

  (II) RADEON(0): CRT2 Monitor: Using vrefresh range of 43.00-72.00 Hz

  (II) RADEON(0): Clock range:  12.00 to 350.00 MHz

  (II) RADEON(0): Not using mode "1600x1200 at 75HZ" (hsync out of range)

  
--------------------


after that the file contains a lot of resolutions with the (hsync out
of range)-error message.



So, this piece i cannot understand


Code:
--------------------
    

  (II) RADEON(0): Not using mode "1600x1200" (no mode of this name)

  (II) RADEON(0): Not using mode "1024x768" (no mode of this name)

  (II) RADEON(0): Not using mode "1600x1200 at 75HZ" (no mode of this name)

  (II) RADEON(0): Total of 2 CRTC2 modes found for MergedFB------------

  (II) RADEON(0): Modes for CRT1: ********************

  (--) RADEON(0): Virtual size is 1600x1200 (pitch 1600)

  (**) RADEON(0): *Mode "1600x1200": 162.0 MHz (scaled from 0.0 MHz), 75.0 kHz, 60.0 Hz

  (II) RADEON(0): Modeline "1600x1200"  162.00  1600 1656 1848 2160  1200 1200 1203 1250

  
--------------------


after that the last two lines are repeatet with different resolution
and values.



And now wierdly it takes the wrong thing and presents me a resolution
on my screen of 640x480:


Code:
--------------------
    

  (II) RADEON(0): Modes for CRT2: ********************

  (--) RADEON(0): Virtual size is 640x480 (pitch 640)

  (**) RADEON(0):  Default mode "640x480": 25.2 MHz, 31.5 kHz, 60.0 Hz

  (II) RADEON(0): Modeline "640x480"   25.20  640 656 752 800  480 490 492 525 -hsync -vsync

  (**) RADEON(0):  Default mode "320x240": 12.6 MHz, 31.5 kHz, 60.1 Hz (D)

  (II) RADEON(0): Modeline "320x240"   12.60  320 328 376 400  240 245 246 262 doublescan -hsync -vsync

  (II) RADEON(0): Generating MergedFB mode list

  (II) RADEON(0): No MetaModes given, linking largest common modes by default

  (II) RADEON(0): Merged "640x480" (640x480) and "640x480" (640x480) to 640x480 (Clone)

  (--) RADEON(0): MergedFB: Virtual width 640

  (--) RADEON(0): MergedFB: Virtual height 480

  (**) RADEON(0): MergedFB: Display dimensions: (305, 229) mm

  (**) RADEON(0): MergedFB: DPI set to (53, 53)

  
--------------------




so and now continues with unimportant stuff (loading module "fb"
etc...)



I tried changing the Horizsync-Value to 31.0 - 80.0 - but didnt help
me.



Hope that y documentet well, so you can unserstand something.

Thank you for helping!
