Description Aaron Brown 2001-02-09 23:13:39 UTC
During a GUI installation (NFS-Full, FTP-Full, HTTP-Laptop), I chose
1024x768x16 for my display settings.  Upon reboot, the system was set to
640x480x16.

This problem doesn't exhibit itself after a TUI installation.  Also, during
"test settings" the correct resolution is diplayed.

Comment 1 Aaron Brown 2001-02-09 23:27:25 UTC
I meant...
GUI: NFS-Full
TUI: FTP-Full, HTTP-Laptop

Also, I tried this with qa0207-qa209.

This defect is considered MUST-FIX for Florence Release-Candidate #1

Comment 3 Brent Fox 2001-02-14 09:09:49 UTC
Is the XF86Config file right and the resolution just comes up wrong, or is the
file incorrect?

Comment 4 Aaron Brown 2001-02-14 10:03:24 UTC
Brent, here's what I've found:

Even though I picked everything correctly during the install, a post install
check of XF86Config shows:

"800x600", "Generic Monitor".  (I was wrong about 640x480, just looked like it.
Sorry)

When I manually change it to "1024x768", "Generic Laptop Display 1024x768", it
works like a champ.


Comment 5 Matt Wilson 2001-02-14 14:25:10 UTC
so user error - picked wrong LCD screen setting.


Comment 6 Aaron Brown 2001-02-15 22:57:02 UTC
Re-opening, per Matt's recommendation.
Still not working.  In my above comment, when I say "manually change", I mean
"running Xconfigurator" from the shell as root.



Comment 7 Aaron Brown 2001-02-16 07:07:22 UTC
Tried inserting "linux vga-787" at bootup.  Didn't have any effect.


Comment 8 Brent Fox 2001-02-16 20:30:34 UTC
Interestingly, this does not happen in TUI mode.  Also, testing X at 1024x768
results in a correct file written to /tmp/XF86Config.test during the install.
After package installation, however, the wrong settings are written to the
/mnt/sysimage/etc/X11/XF86Config-4 file.  This doesn't make much sense.

Comment 9 David Sainty 2001-02-17 22:53:08 UTC
I presume the mobility is on a notebook with built-in LCD.  What is the model of
notebook? Can you give any more information, e.g. ddcprobe output, or the
original XF86Config-4 file that's written to the disk?

I have access to several notebooks with mobility chipsets, but I do not believe
I have seen the bebaviour where you select 1024x768, but "800x600" is actually
set in the XF86Config-4 file...


DS..

Comment 10 Brent Fox 2001-02-20 17:10:04 UTC
I've seen it happen on a Compaq Presario 1700T and Aaron's is a Dell Latitude
CPx.  Both have the ATI Rage Mobility with 8MB of vram.

Comment 11 Brent Fox 2001-03-01 05:35:22 UTC
This problem is due to a bug in iw/xconfig.py.  I have a fix for it, but I'm
waiting for permission to check it into CVS.

Comment 12 Brent Fox 2001-03-01 16:39:00 UTC
The update has now been committed to cvs.  Brock, this is a large change to the
code, so if you have time to double check me here, it would be appreciated.
I'll be testing this today as well.  The change affects the x configuration
screen in general, not just the Rage Mobility.  It just so happens that this
video card exposed a bug in xconfig.py that had been there for a while.
