Cheers, Julien I moved it away and restart X but X fails to start.

Sadness. Can you attach your xorg.conf then?
Cheers,

my xorg.conf
(In reply to comment #4) > Created an attachment (id=16046) [details] > my xorg.conf > I've attached the xong.conf, note that when I enter modelines in the correct location, the intel driver ignores them and probes for modelines anyway. What is your PC model? It seems that there are two VGA ports on your PC, one is from the internal VGA output and the other is from SDVO-VGA (VGA-1 in xorg log), would you please try to connect your monitor on the other VGA port and have a try?
For a temporary workaround, you need to add
1. Option "Monitor-VGA-1" "MB24W" to your device setcion
2. then add the following lines to your monitor (MB24W) section
HorizSync 30-74
VertRefresh 50-61
Option "maxclock" "160MHz"
modeline 1920x1200_OK 154 1920 1968 2000 2080 1200 1203 1209 1235 -hsync +vsync
Option "PreferredMode" "1920x1200_OK"
It seems that our driver fails to get the EDID data from your monitor on the SDVO-VGA output (i.e VGA-1 from xrandr), and then uses the default hsync & vert sync rate which filters out your 1920x1200 mode.
So the real problem is why we failed to get the EDID data from your VGA-1 output, Would you please attach xorg log with option modedebug turned on?
Thanks,
Hong

As as I understand it this SDVO port is a pass-through from the PCI, but I have no PCI cards installed so I cannot use it. The monitor is connected to the sole VGA port, which seems to be linked to VGA-1. I tried putting the above in my xorg.conf, but when I restarted X it just fell back to the VESA driver. I added the modedebug option and have attached it. Cheers, Tom Created attachment 16073 [details]

There may be some motherboard has on-board sdvo controller, what is your PC model and what is the motherboard model? BTW, would you please try a newer driver (2.1.1 may be too old)? Thanks, Hong looking for bug reporter's response to comment# 9 reject this bug due to no response from bug reporter. please feel free to reopen if you have response to comment#9. thanks. |

Created attachment 16028 [details] Xorg log I just bought a new 24" monitor and a new PC with Ubuntu Gutsy pre-installed. The processor is a Q6600 with the G33/31 graphics integrated. The lspci output is as follows: 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 02) When I plug in the monitor I was cannot use the maximum resolution 1920x200. I see from the Xorg.0.log that (II) intel(0): Not using default mode "1920x1200" (vrefresh out of range) It then probes for modes it can use and discovers: (II) intel(0): Printing probed modes for output VGA-1 (II) intel(0): Modeline "1280x800"x60.0 83.46 1280 1344 1480 1680 800 801 804 828 (49.7 kHz) (II) intel(0): Modeline "1280x768"x60.0 80.14 1280 1344 1480 1680 768 769 772 795 (47.7 kHz) (II) intel(0): Modeline "1024x768"x60.0 65.00 1024 1048 1184 1344 768 771 777 806 -hsync -vsync (48.4 kHz) (II) intel(0): Modeline "800x600"x60.3 40.00 800 840 968 1056 600 601 605 628 +hsync +vsync (37.9 kHz) (II) intel(0): Modeline "640x480"x59.9 25.18 640 656 752 800 480 490 492 525 -hsync -vsync (31.5 kHz) None of which are 1920x1200! So my first thought is that the EDID information is broken but get-edid returns the following: Section "Monitor" # Block type: 2:0 3:fc Identifier "MB24W" VendorName "NTS" ModelName "MB24W" # Block type: 2:0 3:fc # Block type: 2:0 3:fd HorizSync 30-74 VertRefresh 50-61 # Max dot clock (video bandwidth) 160 MHz # Block type: 2:0 3:ff # DPMS capabilities: Active off:yes Suspend:no Standby:no Mode "1920x1200" # vfreq 59.950Hz, hfreq 74.038kHz DotClock 154.000000 HTimings 1920 1968 2000 2080 VTimings 1200 1203 1209 1235 Flags "-HSync" "+VSync" EndMode # Block type: 2:0 3:fc # Block type: 2:0 3:fd # Block type: 2:0 3:ff EndSection Which looks perfectly correct! If I force this modeline with xrandr, then the display works beautifully. Unfortunately I cannot figure out: a) how to force the intel driver to use a modeline - it always ends up probing for them b) why the intel driver does not come up with the correct mode from the edid I am using whichever version of the intel driver is included with Ubuntu Gutsy, so I am sorry if this bug has been addressed in later releases. I did try upgrading to the latest Hardy repositories and it still did not work. Apologies if this has been addressed. tpp
