Description Dave Russell 2007-02-02 13:28:33 UTC
Description of problem: system-config-display correctly selects 1920x1200 both as the correct resolution and that I have a 1920x1200 display. However the maximum resolution I have been able to get it to display is 1600x1200. The highest resolution I am able to get it to display is 1600x1200. Version-Release number of selected component (if applicable): xorg-x11-drv-i810-1.6.5-10.fc6 xorg-x11-server-Xorg-1.1.1-54.fc7 915resolution-0.5.2-4.fc6 How reproducible: Every time. Steps to Reproduce: 1. Set 915resolution in rc.local to patch 3c, 4d and 5c from 1920x1440 to 1920x1200 2. Configure xorg using system-config-display 3. Start X, and see the maximum resolution displayed is 1600x1200 :o/ Actual results: 1600x1200 is the maximum resolution displayed. Regardless of what is set in the xorg.conf file Interestingly if I patch the 1600x1200 resolutions to 1920x1200 then X displays at the next lowest resolution reported by 915resolution, 1280x1024. Expected results: 1920x1200 Resolution Additional info: [root@luggage ~]# 915resolution -l Intel 800/900 Series VBIOS Hack : version 0.5.2 Chipset: 945G BIOS: TYPE 1 Mode Table Offset: $C0000 + $269 Mode Table Entries: 27 Mode 30 : 640x480, 8 bits/pixel Mode 32 : 800x600, 8 bits/pixel Mode 34 : 1024x768, 8 bits/pixel Mode 38 : 1280x1024, 8 bits/pixel Mode 3a : 1600x1200, 8 bits/pixel Mode 3c : 1920x1200, 8 bits/pixel Mode 41 : 640x480, 16 bits/pixel Mode 43 : 800x600, 16 bits/pixel Mode 45 : 1024x768, 16 bits/pixel Mode 49 : 1280x1024, 16 bits/pixel Mode 4b : 1600x1200, 16 bits/pixel Mode 4d : 1920x1200, 16 bits/pixel Mode 50 : 640x480, 32 bits/pixel Mode 52 : 800x600, 32 bits/pixel Mode 54 : 1024x768, 32 bits/pixel Mode 58 : 1280x1024, 32 bits/pixel Mode 5a : 1600x1200, 32 bits/pixel Mode 5c : 1920x1200, 32 bits/pixel
Comment 1 Dave Russell 2007-02-02 13:28:33 UTC
Created attachment 147221 [details] xorg.conf with as many of the options as possible enabled for 1920x1200 resolution
Comment 3 Adam Jackson 2007-02-05 20:28:47 UTC
Standard disclaimer: 915resolution isn't supported, etc. I can't figure out offhand why it's claiming "no mode of this name", since there pretty clearly is one of that name even in the VBE dump. There's only like four places where that failure code can come from within the server, and I don't see immediately why you'd be hitting any of them. Checking though.
Comment 4 Dave Russell 2007-02-05 20:42:04 UTC
OK, thanks for looking at this, several questions immediatly spring to mind, one is why it goes to the next lowest resolution if I patch the 1600x1200...? Secondly, how far are we away from using the "modesetting" branch of xorg? As I understand it that will remove the need to use 915resolution, is that correct? Looking forward to hearing more, I'm away from the machine, but any tests you want I can run at the end of the week.
Comment 5 Adam Jackson 2007-02-12 19:19:41 UTC
We're looking at making the modesetting driver the default for i915 and newer for FC7, which would remove the need for 915resolution, yes.
Comment 6 Dave Russell 2007-02-19 05:36:39 UTC
I just found out that we already package the new driver, and sure enough, if I change the driver in xorg.conf from i810 to intel... it works, 1920x1200 with no 915resolution needed. ajax, if you can confirm that this all looks ok, or is at least expected behaviour then I'm happy for either of us to close this.
Comment 7 David Juran 2007-02-21 15:34:24 UTC
Dave, which kernel are you using? I found that with 2.6.19-1.2911.fc6 (and the i810 driver) if I boot the xen kernel I only get 1600x1200 while with the "vanilla" kernel I get the full 1920x1200. Is this the same issue?
Comment 8 David Juran 2007-02-22 15:03:15 UTC
No, my problem seems to be a different one from Dave Russel's. I've buggered off and created Bug 229652 about my issue.
Comment 9 Adam Jackson 2007-04-10 22:31:02 UTC
i810 video support in rawhide (as of tomorrow) will use the intel driver by default for all 945 and 945 chips, as well as 915GM laptops. Marking as resolved in rawhide, but please reopen if this comes back or if you have problem with F7.
