Subject: wrong screen size reported by xinerama

[Message part 1 (text/plain, inline)]

Package: xserver-xorg-core
Version: 2:1.3.0.0.dfsg-2
Severity: normal

--- Please enter the report below this line. ---

Hi,

I'm using nvidia video adapter with dual screen setup: one is LCD panel 
(1440x900) and another one is TV (800x600). They are separate screens (no 
TwinView) and Xinerama is disabled in xorg.conf. But after latest xorg 
upgrade I've noticed that Xinerama is enabled on both screens and that the 
Xinerama screen dimensions are wrong. Here's the proof:

[busa@stratosphere 09:12:57 xineramainfo]$ DISPLAY=:0.0 ./xinerama-info
Xinerama is enabled on :0.0 (1 screen(s) available)
Xinerama screen 0: 1440x900+0+0
[busa@stratosphere 09:15:30 xineramainfo]$ DISPLAY=:0.1 ./xinerama-info
Xinerama is enabled on :0.1 (1 screen(s) available)
Xinerama screen 0: 1440x900+0+0

xinerama-info is a simple C program, which queries Xinerama info from the 
server. I'm attaching its source just in case. Also attached is gzipped 
xdpyinfo output.

Please note that this likely has nothing to do with nvidia drivers, since when 
I was using 1.2 version of xserver-xorg-core everything was fine, and with 
1.2.999 I had exactly the same issue.

Thanks,
Roman

Subject: wrong screensize

Date: Sat, 5 May 2007 11:10:43 +0200

This is not limited to NVidia either; I get the same problem with the
intel-driver.

When I start X on my x60s from the dock (where I also have an external
screen connected), both the internal and external display will get the
resolution from the external display; before it'd use the resolution of
the internal display.  This is highly annoying, since the external
display has higher resolution than the internal.  So when I undock again
I'm left with a laptop that I cannot use in a sane manner because 25% or
so of the desktop is outside of the physical screen.

The only way to get it working is to start the X when undocked, then
dock and run xrandr --auto; that way the external display is properly
enabled at the same resolution as the internal display.

You can't reduce the virtual resolution with xrandr at that point?

Probably; but it's still a nuisance, since there's no way to execute
xrandr from gdm (for instance), so until I log in I cannot change the
resolution.

The only reasonable *default* IMHO is to use the lower resolution for
both screens when using mirrored mode, since that's the only option that
will made things look mirrored (or possible to use the resolution
of the main screen).

Having the configurable is fine by me (I guess some people might find it
useful), but manually invoking xrandr isn't...

Redhat has a patch for this issue:

http://cvs.fedora.redhat.com/viewcvs/rpms/xorg-x11-server/devel/xserver-1.3.0-less-randr-fakerama.patch?rev=1.1&sortby=date&view=auto

Given the author of the patch, it looks like a good bet until it's fixed
in a release upstream.

Thanks, it's applied upstream since april 25th, commit
9c80eda826448822328bb678a7d284cc43fffb17
If it helps, there is probably no reason to not apply it.

   [ Brice Goglin ]
   * Add 24_hurd_ioperm_fix.diff to fix xf86Enable/DisableIO on Hurd with
     recent GNU Mach. Thanks Samuel Thibault!
   * Add 06_use_proc_instead_of_sysfs_for_pci_domains.diff since sysfs-based
     PCI management code is broken at least on sparc and powerpc.
     Closes: #422077, #422095. Thanks to Jim Watson for testing!
   * Install the Xephyr README, closes: #395888.
   * Update 07_xorgconf_manpage_overhaul.diff to drop the reference to the
     xorg.conf example which we do not install since Xserver 1.3 does automatic
     configuration, the manpage is very well documented, and we generate a
     config file during installation. Closes: #222932.
   * Fix warning in /etc/init.d/xprint when /usr/lib/X11/fonts does not exist.
     Closes: #422352. Thanks Cristian Ionescu-Idbohrn!
   * Pull upstream commit 9c80eda826448822328bb678a7d284cc43fffb17 to disable
     RandR's fake xinerama geometry when there's more than one protocol screen
     (closes: #420679).

   * Add patch to make sure that the ramdac symbols are present in the server
     and drivers can use them (closes: #423129).
   * xserver-xorg-core Conflicts with fglrx-driver, which broke with 1.3.
     We'll need to make this versioned (or drop it) when fglrx is fixed.
