The maximum resolution is shown as 800 x 600 on the 8.10 Alpha 5 release

Geforce 2 MX Integrated graphics

Hi pshahmumbai,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

All the above attachment are from Live CD without any changes.

I have to manually add these lines to xorg.conf to enable higher resolution

We are sorry for not being able to give feedback to your bug report earlier.

I am not an expert at Xorg, but it does looks like X was not able to connect to your monitor
to read it's supported modes, synchronization speed capabilities, etc:
(II) NV(0): I2C bus "DDC" initialized.
(II) NV(0): Probing for EDID on I2C bus A...
(II) NV(0): I2C device "DDC:ddc2" registered at address 0xA0.
(II) NV(0): I2C device "DDC:ddc2" removed.
(II) NV(0): ... none found
(--) NV(0): HW is currently programmed for CRT
(II) NV(0): Using CRT on CRTC 0
(--) NV(0): VideoRAM: 8192 kBytes
(==) NV(0): Using gamma correction (1.0, 1.0, 1.0)
(II) NV(0): Configured Monitor: Using default hsync range of 31.50-37.90 kHz
(II) NV(0): Configured Monitor: Using default vrefresh range of 50.00-70.00 Hz
(WW) NV(0): Unable to estimate virtual size
(II) NV(0): Clock range: 12.00 to 350.00 MHz
(II) NV(0): Not using default mode "640x350" (vrefresh out of range)

What is the mark and model of your monitor?

Because it has been a long while since you reported this bug, it could be interesting to test it with upcoming Jaunty version to make sure the issue still happens there with the latest code. ISO images are available at http://cdimages.ubuntu.com/daily/current/ - if you can reproduce it in the LiveCD environment, you shouldn't need to modify your installed system.

Samsung SyncMaster 763DFX

[Paul Dufresne (paulduf)]

Maximum Resolution
1280 Dots, 1024 Lines @65Hz
Active Display
Horizontal 312 ± 4 mm
Vertical 234 ± 4 mm
Synchronization
Horizontal 30 ~ 70 kHz
Vertical 50 ~ 160 Hz

Recommended Mode 1024 X768/85Hz

And it should support Plug&Play:
DDC 1/2B/2Bi Yes

[Paul Dufresne (paulduf)]

It may seems a bit dump question but did you make sure the monitor plug was well connected?
(in case video signal would pass, but not plug&play signal)

Do you intend to try the 9.04 Beta CD ?

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
