bizarre colors on hdmi for Toshiba 42hp95

[mahesh]

After much fiddling using randr -a and plugging in hdmi after boot up I am able to see Ubuntu desktop on hdmi output to Toshida 42hp95, but comes with bizarre overlaying purple or green color. I have installed in XP on the same system and the hdmi functions for both display and bootup from install disc. If I try to bootup on Ubuntu using hdmi only, I get text display for a few lines, then a continual gfxboot error that goes in an infinite loop. Typing help or escape does not seem to help. I am using a 2500 core i5 processor on an Asus P8H67-M evo board with the latest bios which I just updated. I think other folks had problems with display of odd colors which apparently occurred with newer versions of the linux kernal. I am wondering it this will be fixed in upcoming releases, and would be interested in notification if this is under consideration or possible.

I am using Ubuntu 11.04 Kernal 2.6.38-8-generic and Gnome 2.32.1

Do you know your graphics card model by any chance?

I am on Ubuntu 11.04 Natty with kernal 2.6.38-8 generic, with 3.8 GB RAM. I am using a Core i5 processor with integrated graphics. There is no separate graphics card, although I did try a discrete card and still had trouble. The problem occurs with hdmi to hdmi connection, or even a DVI (computer) to HDMI connection. I am using an Asus P8H67-M Evo board. The problem also occurred with 2 of these boards, as well as a Gigabyte H55N-USB3 microATX board,

A randr -a command yields modes of:
1024x768 (0X48) 65.0 MHz
800x600 (0X459) 40 MHz
800x600 (0X4a) 36 MHz
848x480 (0x4b) 33.8 MHz
640x480 (0x4c) 25.2 MHz

Thanks for the info. Assigning package.
