Posted: Thu Apr 25, 2013 5:43 pm Post subject: cannot display this video mode[solved] |
|
|
I was initially using the kernel OSS drivers for my ati-radeon, I then removed those drivers and emerged the ati-drivers, I then followed the steps in 'http://wiki.gentoo.org/wiki/Fglrx' to setup my xorg with my video card, then I rebooted
I got the error:
Cannot display this video mode
optimum resolution 1280*1024 60HZ
I know this probably has nothing to do with gentoo but can someone help me adjust the resolution from the command line? (this is all I have atm)

blakdeath,
Make friends with wgetpaste and post your /var/log/Xorg.0.log file and your xorg.conf.
There is a line near the top of the log that tells where the xorg.conf file in use is located.
Code: | [ 64.507] (==) Log file: "/var/log/Xorg.0.log", Time: Thu Apr 25 17:56:44 2013
[ 64.508] (==) Using config file: "/etc/X11/xorg.conf" |
How is your display connected to the PC?
HDMI, DVI, 15 pin D ?
That may matter, since display resolution has been reasonably well auto detected for a long time now.
Is your display CRT or a flat panel? _________________ Regards,

here's my log file: http://pastebin.com/qFwRe7qH
and here's that conf line: (==) Using config file: "/etc/X11/xorg.conf"
my screen's connected using a 15 pin d cable, and it's a flat panel screen
it's a crappy screen though, so I'm wondering if the resolution is too high for hte screen |

blakdeath,
Your display is advertising that it can do from "1600x1200"x60.0 and all lower resolutions.
I would have expected 1600x1200 to be chosen.
It also says Code: | [ 8.334] (II) fglrx(0): Cannot get EDID information for CRT2 |
As you use the 15 pin analogue connector, that message often means that the connectors are not full home.
Can you post the content of /etc/X11/xorg.conf please. _________________ Regards,

blakdeath,
In what resolution?
Some displays lie to xorg in their EDID data.
What display do you have ? _________________ Regards,

blakdeath,
Thats the display manufacturer and it tells that its Digital Flat Panel 0, which is the first/only display.
The model number is usually close to there in the log file too. _________________ Regards,

blakdeath,
Its a Dell.
That data sheet says 1280x1024 is as good as it gets.
Dell never made monitors, so its a rebadged something else. Dell generally chose good stuff to put their name on. _________________ Regards,
