Dell 2405FPW and resolution 1920x1200

[Thunder.m]

Latest Ubuntu Edgy Eft still canot recognize my monitor Dell 2405FPW and working in resolution 1600x1200. I have to manualy edit xorg.conf file to enable resolution 1920x1200. I have Nvidia GeForce 6800GS PCI-E and monitor is connected to DVI and D-SUB.

[Vassilis Pandis (pandisv)]

Is this still a problem with latest Dapper/Edgy ?

[H3g3m0n (h3g3m0n)]

I also have this problem in Edgy, System has 1600x1200 4:3 instead of 1920x1200, usplash has 1024x768 in its conf.

Video card is a nVidia 7600GT:
05:00.0 VGA compatible controller: nVidia Corporation Unknown device 0391 (rev a1)

Looks like the resolution in xorg is screwed, the default mode lines in xorg.conf for all colour depths are:
Modes "1680x1680" "1600x1200" "1280x1024" "1152x864" "1024x768" "800x600" "720x400" "640x480"

I'm guessing that 1680x1680 is supposed to be 1920x1200.

Also looks like another bogus resolution is in there, in xorg log:
(WW) NVIDIA(0): No valid modes for "1680x1680"; removing.
(WW) NVIDIA(0): No valid modes for "720x400"; removing.

And also:
(II) NVIDIA(0): Validated modes:
(II) NVIDIA(0): "1920x1200"
(II) NVIDIA(0): "1600x1200"
(II) NVIDIA(0): "1280x1024"
(II) NVIDIA(0): "1152x864"
(II) NVIDIA(0): "1024x768"
(II) NVIDIA(0): "800x600"
(II) NVIDIA(0): "640x480"

Can you please attach og/Xorg.0.log and /etc/X11/xorg.conf files to this bug. Thank you for reporting this bug with us.

[Sarah Kowalik (hobbsee-deactivatedaccount)]

To the original reporter: what kind of video chipset & card do you have?

[Thunder.m (thunder-m)]

I have Nvidia GeForce 6800GS PCI-E (Leadtek).

[H3g3m0n (h3g3m0n)]

Attached is the xorg.conf file the livecd creates by default, this file seems to be the same one that dpk-reconfigure makes in non interactive mode.

[H3g3m0n (h3g3m0n)]

Same for log.

[John Vivirito (gnomefreak)]

From what i see after working with you on IRC that its not setting any refresh rates at all that would be why your not getting correct resolutions. if you add refresh rates to it manually in /etc/X11/xorg.conf and save it restart X do you get the res. you want? you might have to add the res you want to it also. After some checking your monitor is a LCD widescreen. your refresh rates are as listed.
vertical the max is 76 Hz and horizontal max is 81 kHz. I didnt see a minimum. im gonna look into the other bugs we talked about this morning on IRC and i think hobbsee was right they are duplicates but i will let you know.

[John Vivirito (gnomefreak)]

I marked bug #48075 as a duplicate of this bug. please see logs on original bug if they are needed.

[Marco Cimmino (cimmo)]

Ok I'm from the last duplicate :)
I've tried kubuntu feisty herd 1 and the problem persists with my Acer AL1952 a 19" 4:3 (non wide) that is recognized @1024x768x60hz instead of 1280x1024x60or75hz

Why this bug is still marked needs info? I can provide if needed.
There is a way to see fixed for final Feisty?

Thanx

[Marco Cimmino (cimmo)]

Still the same with Feisty Herd cd 2 and my Acer AL1952 19"

[Marco Cimmino (cimmo)]

confirmed in herd cd 4

[Marco Cimmino (cimmo)]

and still here with herd cd 5
no fix for Feisty?

[Timo Aaltonen (tjaalton)]

xresprobe needs love.

could you post the result of 'sudo xresprobe $DRIVER' (substitute with the driver you are using)

[Marco Cimmino (cimmo)]

Timo very strange:
here with Kubuntu Edgy 6.10 full updated, nvidia proprietary driver and Acer AL1952 19" this is the result:
marco@b-52:~$ sudo xresprobe nvidia
id:
res:
freq:
disptype:

tried Feisty snapshot 3 March 2007, driver nv, same LCD:
ubuntu@ubuntu:~$ sudo xresprobe nv
id:
res:
freq:
disptype:

what can be the problem?

thanx

[Timo Aaltonen (tjaalton)]

that's something I'd like to know as well :) Can you try with dapper live-cd what it says?

[Marco Cimmino (cimmo)]

Timo same identical thing with dapper 6.06.1 live cd and nv driver...

[Timo Aaltonen (tjaalton)]

I've had the Dell myself, and I believe that it gives bogus DDC-data.. Could you try running without xorg.conf with herd5, to see if the xserver manages to get the correct data out of the monitor.

[Marco Cimmino (cimmo)]

Timo how can I do it?

[Timo Aaltonen (tjaalton)]

move the xorg.conf (rename it to xorg.conf-old or something) and start gdm (or whatever you are running). The new xorg-server works without a conffile.

[Marco Cimmino (cimmo)]

Yes Timo, tried Feisty snapshot - 3 March Live cd and at boot my Acer AL1952 as always has wrong 1024x768 resolution after deleting xorg.conf file I have tried ctrl+alt+backspace and after that X restarted with a correct 1280x1024

Timo I've not the Dell because I'm not the reporter but I have the same problem.

[Marco Cimmino (cimmo)]

so there is a chance to see fixed for Feisty?
I can test binary if someone fix it ;)

[H3g3m0n (h3g3m0n)]

Removing xorg.conf results in the correct resolution on my Dell 2405FPW under Fiesty dev

The xresprobe returns 1680x1680 instead of the correct resolution of 1920x1200:

root@ender:/etc/X11# xresprobe nv
id: DELL 2405FPW
res: 1680x1680 1600x1200 1280x1024 1152x864 1024x768 800x600 720x400 640x480
freq: 30-81 56-76
disptype: crt

[Timo Aaltonen (tjaalton)]

"disptype: crt"

that means something is wrong... could you post the 'ddcprobe' output

This is using the nvidia binary driver btw.

[H3g3m0n (h3g3m0n)]

Heres mine using the nv drivers, both ddcprobe and xresprobe cause the display to corrupt when run, but changing virtual terms fixes it, I assume its a nv driver bug.

[Timo Aaltonen (tjaalton)]

ddcprobe returns correct values, but xresprobe somehow doesn't mangle them. Could you try running xresprobe in console, shutting X first down? And what does /usr/share/xresprobe/ddcprobe.sh give?

[Hidde Brugmans (hcbrugmans-deactivatedaccount)]

xresprobe (same for both nv/nvidia)
it reports the monitor as crt, it is in fact an lcd.

[Hidde Brugmans (hcbrugmans-deactivatedaccount)]

ddcprobe.sh output (identical)

[Timo Aaltonen (tjaalton)]

Ok, this was pretty simple in the end.. The reason why the maximum resolution is not used is because ddcprobe lists the device as being 'crt', and for those devices the highest resolution is cut off (since it rarely is usable).

I'll try to make a fix for this, let's hope it gets in Feisty.

[Marco Cimmino (cimmo)]

great Timo! Thanx!!

[Timo Aaltonen (tjaalton)]

ok, first try:

http://users.tkk.fi/~tjaalton/xorg72/new/xresprobe_0.4.24ubuntu3.1_i386.deb

that has the Dell listed in /usr/share/xresprobe/lcdlist, and /usr/share/xresprobe/ddcprobe.sh tries to grep $MONITORNAME from it. Cimmo, could you run 'sudo ddcprobe | grep monitorname' so we can add your monitor to the list, in case it outputs anything...

[Marco Cimmino (cimmo)]

Timo here with Edgy something wrong with ddcprobe, it fails and die with "edid", should I try with Feisty?

[Hidde Brugmans (hcbrugmans-deactivatedaccount)]

timo,

your package fixes the bug for me. I have dpkg-reconfigured xserver-xorg to be sure and it came up flawlessly in 1920x1200 resolution after a reboot.

Thank you.

[Marco Cimmino (cimmo)]

Timo with Kubuntu Feisty Beta identical situation as described by my last comment.

What can I do?

[Timo Aaltonen (tjaalton)]

Feisty is about to release, and the solution I planned isn't really a good one so it won't be uploaded.. Things are going to change a lot for Gutsy anyway, so let's keep this bug open until we don't use xresprobe anymore.

[rngadam (rngadam)]

For the record, this problematic monitor is immediately and correctly set at 1920x1200 in Fedora Core 7 test 4 when booting as LiveCD. They don't seem to be using xresprobe either.

[marcnz (mquattrini)]

I have this problem also and the problem is that the patch provided by Timo cannot be applied on the x64 bit version.
Any idea what can be done?
Thanks.

[Brad Fitzpatrick (brad-danga)]

Any progress on this? Anything I can do to help?

Having same problem with this monitor and DVI connection, using either "nv" or "nvidia" drivers. Latest Gutsy Tribe 4 + dist-upgrade as of today.

[Bryce Harrington (bryce)]

Cimmo, btw your bug is different from this one since you get an edidfail result.

For those getting an edidfail, I believe this might be a dupe of 94994.

[Bryce Harrington (bryce)]

Okay:

Those seeing 'edidfail' are probably just dupes of 94994.

Those seeing xresprobe returning "crt" when they really have an "lcd", and it's "losing" the highest resolution, you're seeing bug 27667, which we've got a fix in for.

Those seeing "square" resolutions like 1680x1680, that is probably the same as bug 115220 (1440x1440). Based on the ddcprobe output, either ddcprobe or the monitor firmware is buggy.

Since the original report was basically bug 27667, and all commenter's problems seem to be dupes of other bugs, I'm closing this one as a dupe.
