Screen resolution
Hi,
Please can u help me? I understood i would resolve my res prob by adding 2 lines of monitor spec to my xorg.config. This is my monitor spec Horizontal scan range 30 kHz to 96 kHz Vertical scan range 48 Hz to 120 Hz + Optimal preset resolution 1024 x 768 at 75 Hz or 85 Hz Highest preset resolution 1600 x 1200 at 75 Hz Highest capable resolution 1600 x 1200 at 75 Hz This is how xorg.configt looks with the 2 lines inserted. It hasn't worked ? Section "Device" Identifier "Generic Video Card" Driver "vesa" BusID "PCI:1:0:0" EndSection Section "Monitor" Identifier "ULTRASCANP99" Option "DPMS" HorizSync 30-96 VertRefresh 48-120 Modeline "1024x768@85" 100.94 1024 1056 1432 1464 768 782 793 807 EndSection Section "Screen" Identifier "Default Screen" Device "Generic Video Card" Monitor "ULTRASCANP99" DefaultDepth 24 SubSection "Display" Depth 1 Modes "1280x1024" "1024x768" "800x600" "720x400" "720x350" "640x480" EndSubSection SubSection "Display" Depth 4 Modes "1280x1024" "1024x768" "800x600" "720x400" "720x350" "640x480" EndSubSection SubSection "Display" Depth 8 Modes "1280x1024" "1024x768" "800x600" "720x400" "720x350" "640x480" EndSubSection SubSection "Display" Depth 15 Modes "1280x1024" "1024x768" "800x600" "720x400" "720x350" "640x480" EndSubSection SubSection "Display" Depth 16 Modes "1280x1024" "1024x768" "800x600" "720x400" "720x350" "640x480" EndSubSection SubSection "Display" Depth 24 Modes "1280x1024" "1024x768" "800x600" "720x400" "720x350" "640x480" EndSubSection EndSection |
Now if we knew what exactly your problem is ... or which lines
you added ... The modline is for 1024x768, but the default resolution is 1280x1024 ... Cheers, Tink |
The 2 lines i inserted appear under
Section "Monitor". they are HorizSync 30-96 VertRefresh 48-120 i have removed the next line: Modeline "1024x768@85" 100.94 1024 1056 1432 1464 768 782 793 807 Hoping it would solve the problem. - It hasn't. |

A clarification of my problem ( I hope).
The Dapper screen pref gui default res is 1280 x 1024. This looks most appropriate and i can't alter it to lower resolution in the dropdown. The same applet claims my refresh rate is 86 Hz and likewise i cannot change it, -but my screen looks like 60 Hz, which is the reading my monitor displays when i press a button on the cabinet. This is too low and it trails smears when i move windows. I can lower the the resolution by deleting the 1st settings ( 1280 x 1024 ) from each modes line in the /etc/X11/xorg.conf but i'm sure these are less appropriate settings. Somebody said i could use a different driver? |
VESA certainly isn't optimal; what graphics card does the
machine have? Cheers, Tink |
change the driver type from vesa to your driver
i had the same problem a while ago untill i didn't change vesa to sis then added my resoluion options here: SubSection "Display" Depth 24 Modes "1280x1024" "1024x768" "800x600" "720x400" "720x350" "640x480" EndSubSection |
My graphics card is below; and the vesa driver came with the pc:
SiS Mirage Graphics Section "Device" Identifier "Generic Video Card" Driver "vesa" BusID "PCI:1:0:0" EndSection can i download an alt driver? Oh,oh! Following advice A, B has happened. A: -type "sudo dpkg-reconfigure xserver-xorg" Choose your graphics card/adapter from the list, follow the text, if there's anything you don't understand press "esc" (this will skip). When you come to resolution, enter 1600x1200 with the space-bar. Choose "medium" for the settings, move down to 1600x1200@75Hz. This will give you a range of resoloutions between 1600x1200 and 648x480. B: All seemed to go perfectly well. However when i restarted, the user and password screens appeared, so i tapped in my details... It halts on a black page of text before returning to the user and password screen. There dosen't seem to be a way in? |
Maybe the configuration is already correct and you don't know know how to switch resolutions?
Try going to the desktop and pressing Ctrl Alt + (or) Ctrl Alt - to change your resolution. |

And I'm facing the same problem. I'm using Debian-AMD64-lenny. Currently the screen is configured through vesa, and I only get 1280x1024. The monitor is 17" and I would like atleast 1440x900. Adding the required resolution (1440x900) the xorg.conf file did not help. Then I tried Code:
dpkg-reconfigure -phigh xserver-xorg Code:
No devices detected. Any ideas? |
