Bug Description

Binary package hint: xserver-xorg-video-intel

[Paul: This size 289x21 millimiters is reported by about 6 persons on Intel chipset, I have i945 but
mine is fine]
[Paul: other values seen: 40x30, 10x10 ATI radeon)]

Lure on the kubuntu-devel irc has given me a list of things to report. This report is to fix the following.

The screen res taken from xdpyinfo is
1280x800 pixels (289x21 millimeters)

The dpi taken from xdpyinfo is
112x968 dpi

I will add the log files shortly.

[Update]
This problem is caused by buggy monitors that emit incorrect EDID from their firmware. Fortunately, X.org has a mechanism for working around these bugs, but they're implemented specific to the particular model # of the monitor. So if you find yourself experiencing this problem, please file a NEW bug (don't reopen this one) against xorg-server titled "<monitor-name> produces bad EDID causing large font sizes; needs quirk", and attach the following information:

 * /var/log/Xorg.0.log
 * output from `sudo ddcprobe`
 * output from `sudo get-edid | parse-edid` (you'll need to install the read-edid package)

This patch needs probably go upstream anyway (should go in 1.4.1 as well) as there are often cases when we don't know the physical size of an output and need to specify it. See bug 12474 for example.

You could potentially workaround this issue for at least running KDE session (not for KDM though) by using xrandr in Xsession startup script. You would need to add new file /etc/X11/Xsession.d/35fix-displaysize with the following content:

/usr/bin/xrandr --fbmm 330x210 || true

You need to replace 330x210 with actual size of your display in millimeters (mm).

Side effect of this change is the fact that now fonts are two small - I would need to increase the font size to get some readable font size.
I think this is step back for high-resolution displays (>120 DPI), as they will get fonts (and other UI widgets) smaller then they are defined (in terms of pt).

Just correcting the links from my earlier post:

This commit adds quirks for some monitor models, so that the probed EDID info will be corrected. It will be included in xorg-server 1.5.

This commit fixes the "DisplaySize" option so that it will always override any probed EDID info and be used to calculate DPI correctly. This one will be in xorg-server 1.4.1 (and is already in Hardy).

To give some more information:
I got it working with the correct DisplaySize and I seemed to have gotten it to where the dpi was correct but good god was it slow. I've never seen firefox render anything quite so slowly or a simple picture to load. I was watching it as it scanned from top to bottom...

So, I'm not sure what's going on now. I guess I'll wait. I've spent about two hours trying to get something working to no avail. I'm just reverting back to i810 for now.

Hi Jimmygoon,

Which is the model of your card? it may be helpful for other people that are trying to install Hardy.

As stated previously some monitors report a buggy EDID, in order to fix for you monitor it wil be helpful to provide your /var/log/Xorg.0.log file?

If the intel driver is too slow I'll suggest to open another bug report, well it doesn't seems to be related to this bug.

Jimmygoon (jimmygoon) wrote :

Sorry, I admit I was a bit frustrated earlier and was a tad unwilling to spend much more time with this bug, but today I'm more geared up.

I've attachment my Xorg.0.log. This is basically a result what ubuntu sets up EXCEPT for when I specify the 'i810' driver (like I've stated ubuntu defaults to 'intel'). My graphics card is: Intel Integrated 855GM (Intel(r)852GM/852GME/855GM/855GME)

I think I managed to get it working by specifying DisplaySize but... it was strange. It cause gnome-settings-daemon to crash (every single time and starting it from CLI gave a core segfault) and so it may have been a combination of things leading to a sluggish feel that I was attributing to the intel driver.

So basically, my workaround stands for me of switching back to i810 (I keep saying this in case someone else sees this with the same problem :D)

If someone wants, I'll be around #ubuntu+1 for basically... all day today and most of tomorrow so I can try things at will. I've got another computer so I can get on IRC there and test stuff here and go through different test scenarios if that would be helpful.

* Setting DisplaySize for my Monitor
* Adding the Option "Monitor-LVDS" "Configured Monitor" to my xorg.conf

I don't know why, but those two things APPEARS to get the fonts right (presumably with the intel driver) on my GDM screen and I'm about to check and see if gnome-settings-daemon survives.
How can I check and make sure intel is in use and I'm not wasting my time debugging VESA kicking in? thanks.

Yep, gnome-settings-daemon crashes upon attempt to login ---- "The Settings Daemon restarted too many times"
Attempting to run "gnome-settings-daemon" as superuser from the CLI gives: http://paste.ubuntu-nl.org/59867/

Finally, I'm afraid there is some sort of bug overlap. After implementing the fixes I've described here, I tried to submit a bug report for the gnome-settings-daemon and came across this:
https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/197153
(Note the last comment before mine... describing how that person was suffering this bug on an Intel 855 GM chipset (same as mine)

I hope this is making forward progress. Thanks so much!

For those still having this problem, please file a NEW BUG against xorg-server on it. Include both your /var/log/Xorg.0.log, and the output of `sudo get-edid | parse-edid` (you'll need to install the read-edid package for this).

The problem here is that there is a _hardware_ bug in the monitor - it lies about its capabilities. So each case has to be handled on a case-by-case basis by 'quirking' the xserver to enable the appropriate workaround for that specific piece of hardware.

Since we have to handle each individual problem on a case-by-case basis, it is much easier to do this with separate bug reports, rather than this big one (which is getting hard to follow and keep track of who all is still having problems, and no doubt spamming people for whom the problem is long since solved. *grin*)

@Samuel, I was able to get the necessary info to compose a quirk from your Xorg.0.log, so no need for you to file a new bug.

@puccha, unfortunately your Xorg.0.log did not have detailed EDID info listed so I don't know which quirk to use for you. Please file a NEW bug and attach the info I mentioned above.

A good workaround:
nx7400 - text in login input line is far too big:
Edit gdm.conf file and add the -dpi 96

[server-Standard]
name=Standard server
-command=/usr/bin/X -br -audit 0 -dpi 96

rif. http://gp3d.blogspot.com/2008/08/acer-extensa-5220-and-hp-nx7400-ubuntu.html

That was the final solution for me.
In my personal opinion, this bug can't be solved by the ubuntu team beacause it is caused by a wrong valued on the specified system: an exception must be created but an exception is non a solution... it is just a permanent workaround!

[This is an automatic notice.]

We'd like to forward your bug upstream, however upstream requires
that you first test it against their newer driver code.

To save you the effort of building the driver from source, we've built
packages for the driver and its new dependencies.

So you have a couple options:

 1. Download and test .debs for intrepid, from:
     https://edge.launchpad.net/~intel-gfx-testing/+archive

 -or-

 2. Download and test the Jaunty alpha-2 (or newer) Live CD,
     (which includes a beta of the new xserver 1.6 as well).
     See http://cdimage.ubuntu.com/releases/9.04/ for ISOs

Thanks ahead of time! You can simply reply to this email to report your
findings.

P.S., if you wish to forward your bug upstream yourself, please follow
these directions to do so:
  http://intellinuxgraphics.org/how_to_report_bug.html

I have tested with 8.10 (the official release, not the testing debs) and with Jaunty alpha-3 Live CD. The display size appears to be correctly detected.

Thanks for testing; it sounds like the issue is no longer being seen so I'm closing the bug.

I have also written a page for troubleshooting these kinds of dpi issues, in case others notice these problems in the future: https://wiki.ubuntu.com/X/Troubleshooting/HugeFonts

If anyone sees a wacky font size issue, please follow the troubleshooting guide and file a NEW bug; don't reopen this one.

Alois, can you please add Option "ModeDebug" "true" to your xorg.conf and attach the new log? Apparently there are several panels from Philips with product ID = 0 and not all of them need this quirk. I am wondering if there is some more identification we can use.

yes, but now using xorg-server 1.6 and xf86-video-intel 2.6.99.902

will have any influence?

Reopening as there seems to be other models affected. I'll attach the Xorg.0.log with ModeDebug on for my system as well.

I haven't noticed anyone report this bug on an NVidia card. I have an NVidia GeForce 8800GT and I have huge text in the login manager. I also have huge text in KDE, although GNOME is fine. I'm using the NVidia proprietary driver version 180.44, and the monitor attached is a 26" Samsung TV on a DVI-HDMI link. nvidia-settings is reporting: 1360x768 pixels (161x90 millimeters) and a resolution of 215x217 dots per inch.

This bug report is way too big. The original bug should be fixed, and the reporter no longer has the hardware. If people have bugs with other monitors, please open your own bugs so you actually get some attention!
