Ubuntu, xorg disappointment [Aug. 16th, 2007|10:51 am]

Ubuntu Edge, Feisty, and Gutsy (Tribe 4 + updates as of yesterday) still cannot detect the native resolution / modelines for my Dell 2405FPW monitor, a monitor which is over 2 years old. (with either "nv" or "nvidia" drivers)

C'mon... seriously?

I have the 19" Dell LCD and it's been detected for a long time, with even older Ubuntus. The other day I booted and it came up in 640x480 mode; after some digging I discovered the display cable had become loose enough that the monitor-metadata-reading code was failing, but somehow it was connected enough that it still was displaying ok. Pretty weird!

Try: apt-get install read-edid; read-edid | parse-edid
Maybe it'll dump a modeline or some sort of error?
I can't remember if these monitors still use EDID for configuration, though... looks like the work Ubuntus still use a modeline. :\
(Now that I think about it, I wonder if EDID is even relevant with DVI connections? The Xorg.log from a machine here claims it read the display DPI via EDID...)

Yeah, read-edid | parse-edid was failing, as was xresprobe.

And yes, the cable on the monitor is barely hanging on (not screwed in, and hanging upside down). It kept falling up and I kept pushing it back on.... that'd be really impressive if that was the cause.

I'll give it a second try later and report back.

(although I'm not optimistic, as the Internets is full of reports of this not working still....)

You have a Linux machine with a video card in it? There's your mistake.

I'll try it every 6 months and maybe be pleasantly surprised.

For instance, I was surprised that the latest Ubuntu ships with the Compiz/Beryl/whatever shit on by default .... so I have wobbly windows and shadows and animations and cubes and raindrops and all that bullshit out of the box.... at like 640x480 or something. YAY!

See ya again in 6 months, Ubuntu!

Having compiz/beryl/etc on by default would make me want to stab some X packager.

mine detects and works

I was actually quite pleasantly surprised when I didn't have to edit xorg.conf on my box when I installed Ubuntu.

I have an Apple monitor attached to an nvidia 7xxx-something card, and it all works right. I may have had to enable the restricted-modules stuff (for the nvidia binary non-free driver), but that's about it.

Linux sucks way less than it used to :)

I consider things like that to be two bugs.

One, that they didnt correctly detect it.

Two, that the developers and maintainers havn't made it trivially easy for end users to report gaps in the auto-detection logic.

(And "sign up for our Bugzilla, and then report it as a bug" is a non-starter. Geeks who know how are getting password fatigue on Bugzilla systems, and dont have time to spend the hour plus to get it into the right format to have it paid attention to. And lay end users are stopped cold at the "sign up for our bugzilla" stage.)

And there is no excuse for the packagers to point fingers at the upstream developers. Take the report *anyway*, then rereport it upstream yourself!

I've often thought it odd that someone associated with Xorg hasn't written some little script that takes apart the video card and monitor description CAB files that have shipped with every version of Microsoft Windows back to Windows95, and built an exhaustive database of videocard specifications and monitor specifications.

Let Microsoft do all the work, and then just update the "public database" whenever they push out a Windows Update. :)

I believe that there would be some legal issues intertwined with that somewhere.

... or at the very least, Microsoft would come bitching to the project maintainers with legal threats.

Heh. Read through all of the bug report, not having noticed that you'd already tried Gutsy, and was going to point it out until I got to the last comment...

Ditto. I've not found a monitor it won't detect yet. Even throwing KVM switches in the way doesn't confuse it.

I so always forget how painless it is to use anything in virtual machines ... so then I end up installing something, getting annoyed for driver hunt and just *argh* once more deciding that Linux stays in Workstation and Fusion.
So .. got really annoyed with XP, converted it to a vm, then wiped everything over three day weekend, fought to get some resolution (that was the easiest part) .. and trying to figure how to find the wireless drivers, the secondary display .. the secondary display I gave up after quite screwing up xorg .. couldn't see anything. Sigh. So still AD problems for joining the account ...
and off, time for Corporate XP image, gui made to look like OS X, and whatever I need in Workstation. At least just install it, install tools, maybe look for how to configure somehting but that's it.
Go with Debian, more fun ... :p

Fiesty Blows

On my Dell laptop the Feisty live install CD wouldn't even start X. I had to use the text install version, then apt-get the aiglx ati driver and edit xorg.conf before it would even start X. Even then I still had to edit xorg.conf because it got my screen resolution wrong. Whats even weirder is the live install worked fine in edgy

I had to use gtf in order to get a sane modeline, and be put into the xorg.conf.

DDC failed, manual number crunching failed, etc.
Granted, I don't know how old the Gateway FPD2275W monitor is, but regardless.

I had a problem like yours.
Envy helped.
Maybe it will help in your case?

I spent a week trying to do this. And finally got it, although since I really know nothing about what I'm doing on Linux, I couldn't say what I did! I know I'm using nvidia binary drivers for my Nvidia Quadro FX 540, and whenever it starts to cry, I have to go through another configuration dance with those things, and then use them (and not Ubuntu's configuration utility) to set the resolution.

That then that sometimes doesn't work until I reboot.

Which is lame.
