Description Gantry York 2003-10-17 01:08:35 EDT
Description of problem:

The Screen Resolution (/etc/X11/XF86Config) tool recognizes that I am using a
Riva TNT with a Dell 1626HT monitor, but 1152x864x'millions of colors' at 85Hz
is the highest it will configure it to go.  Yet it can be set for greater than
this.  In fact, when I was running RH9, I had it set to 1600x1200 with the same
hardware configuration.


Version-Release number of selected component (if applicable):

Fedora Core "Severn" beta - Test3


How reproducible:


Steps to Reproduce:
1.
2.
3.
    
Actual results:


Expected results:

I expect it to have 1600x1200 as a possible choice for screen resolution.

Does your XF86Config file actually have the larger resolutions in its Screen
section?
Comment 2 Alexander Larsson 2003-10-17 13:44:46 EDT
This is probably an X issue. What does "xrandr" say if you run it on the command
line?

Reply to Comment #1 (by J Blanford)

No, but that is the whole point.  The installation should detect all the
possible resolutions and create an XF86Conig with all those possible resolutions.

Comment 4 Michael Fulbright 2003-10-20 14:30:23 EDT
Anaconda only tries to setup a basic mode that is known to work. The
redhat-config-xfree86 tool is used to modify this selection.

Due to how XFree86 servers work you cannot write out the higher resolution modes
in the XF86Config file or you will get a virtual desktop. Kinda makes xrandr
useless.
Comment 5 Tino Meinen 2003-10-23 13:18:52 EDT
Same situation with my IIyama Vision Master Pro510 (21") and Nvidia Geforce3 card.
Comparing RH9 XFree86 with the one from FCtest3 shows:

So, the max resolution with anaconda and with redhat-config-xfree86 is 1024x786
wich is not a lot for a 21" monitor.

Gantry: As root, run '/usr/sbin/ddcprobe' and paste the results here.
Comment 7 Brent Fox 2004-03-04 22:19:56 EST
Closing due to lack of information.
