Red Hat Bugzilla – Bug 151856
GUI goes off bottom of screen on Mac Mini
Last modified: 2007-11-30 17:11:02 EST
Description of problem:
When anaconda starts up in GUI mode only the top left 1/4 of the installer is
visible on the screen. Buttons, etc are all off the bottom of the screen.
Version-Release number of selected component (if applicable):
attempt to install
Steps to Reproduce:
Hardware is a Mac Mini (ATI Radeon 9200)
May or may not be relevant but during the detection phase the monitor comes back
as unknown, however the same monitor when connected to an Intel machine is
Would you be able to provide some diagnostics as required?
In particular you fail to mention the make/model of the monitor.
With the intel box and this monitor can you attach /etc/X11/xorg.conf and also
seperately the output of running as root /usr/sbin/kudzu -p -b ddc
When the ppc box is booted into the installer can you go to a shell (ctrl-alt-f2
(may involve using the fn key to shift F keys)) and also give me the output of
python -c "import kudzu; print kudzu.probe(kudzu.CLASS_UNSPEC, kudzu.BUS_DDC,

Segmentation fault is the result of this.

xorg.conf from a fresh install of FCT1, not optimal as monitor is capable of
doing 1024x768 even though it is not listed.

Wanna take a gander at this with FC4t3? I can't reproduce. What is however funny
is that when you ran a ddcprobe in comment #4, you got back nvidia riva tnt
(when this is clearly an ati radeon)
I just booted up the installer for FC4t3 and nothing has changed, the gui is
still off the screen. Regarding comment #4 that was the result of a request for
information from an Intel based box that shares the monitor in question. On the
Intel box the installer correctly identifies both the video card and monitor,
however on the Mac while the ati radeon is identified it reports back unkown
Does X work fine after the install?
Yes X is working fine once installed.
Hrmm... does the X config differ between post-install and during the install?
You should be able to just start the installer and grab the X config from /tmp
and then diff it to your regular X config.
In the Screen section during install there is only an entry for 640x480
The other difference seen is in the Monitor section.
During the install there is the following 2 lines:
HorizSync 31.5 - 37.9
VertRefresh 50.0 - 70.0
The file created by system-config-display has the following:
HorizSync 30.0 - 96.0
VertRefresh 50.0 - 160.0
During the install going through /tmp/ramfs/X.log revealed the following errors:
640x480 vrefresh out of range
640x480 hsync out of range
This is also repeated for a lot of other resolutions with these errors.
We've done some work on how X starts up in anaconda for this next release. Is
this working better in FC5test3?
Closing due to lack of response from reporter.
If this still occurs with FC5, please reopen.
