Red Hat Bugzilla – Bug 495019
GUI dialogs with xdriver=vesa exceed the screen size
Last modified: 2009-05-08 13:39:39 EDT
Description of problem:
When booting anaconda with the "Install system with basic video driver" option, all the GUI dialogs are larger than the desktop, making it virtually impossible to navigate. The display reports however that the video adapter is in 640x480 mode. Also the desktop is not larger than the screen. The mouse stops at the edges of the screen.
Version-Release number of selected component (if applicable):
184.108.40.206 (on the Beta DVD)
Steps to Reproduce:
1. Choose "Install system with basic video driver"
2. Observe the GUI dialogs run beyond the desktop
The dialogs exceed the screen size
The dialogs should fit on the screen
00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02)
I eventually had success using keyboard shortcuts for items that were off the screen. If it helps, part way through boot to runlevel 3, the machine switched to 1600x1200 vga text mode spontaneously. (1600x1200 is my display resolution.) nomodeset works as a kernel parameter on the running system to stop that.
Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.
Please attach your X server config file (/etc/X11/xorg.conf, if available) and X server log file (/var/log/Xorg.*.log) from the running system to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below.
Could you please also add /var/log/anaconda.xlog?
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.
I don't currently have X on the subject system, so there's no xorg.conf or Xorg.*.log. It will be a little challenge to add X, but it's doable.
In the meantime, I'll add anaconda.xlog.

anaconda.xlog with xdriver=vesa
X installed from DVD. No rawhide.
It appears to work fine with the intel driver.
Too bad the same isn't true in anaconda.
Attaching xorg.conf and Xorg.0.log.

I experienced the bug you reported (Bug 495032), which lead me to this bug. I've tried to recreate this bug with two separate machines that also have the 865G graphics, and have been unsuccessful. However, I've only been able to test with monitors whose highest resolutions are 1280x1024 and 1680x1050. The one thing I noticed was that when installing with the 1680x1050 monitor, anaconda actually used 1280x1024 resolution. This makes me wonder if the problem is specific to the 1600x1200 resolution that you're using. Do you have another monitor with a lesser resolution on which to test this?
For the record, I'm not part of the team fixing this - I'm just an interested beta tester who wants to help.
1600x1200 is the only monitor I've got. Sorry.
The xorg files and the kernel that anaconda uses appear to be the same as the ones installed. Once installed, everything runs fine. It's just in anaconda that the GUI is screwed up.
So here's a simple question that occurs to me.
The video card has 1M of memory.
The vesa driver figures out that 1M of RAM means 640x480x16bpp.
You can read that in the anaconda.xlog file.
Is the essence of the problem that something no longer knows how to deal with a graphics area as small as 640x480?
Anaconda's UI has never been able to deal with anything smaller than 800x600. Don't know why you were trying to install with vesa though, it's really a last resort kind of thing.
800x600 would work, except it doesn't.
Can you make 800x600 work, since that's your criterion?
Regarding 800x600 being the lowest res mode, from
Force GUI installer to run at 640x480
As to why I'm using the vesa driver...
Well, the intel driver is even more broken (invisible mouse) and text mode had a bunch of functionality ripped out. But whatever the reason, if somebody needs the last ditch resort, shouldn't the last ditch resort work?
"Force" means "even though the UI will have lots of elements offscreen, do it anyway", not "resize the UI to be smaller".
It would be lovely if the vesa driver worked in all cases, but there's any number of reasons why it might fail. It does very little more than call to BIOS routines to set up the video mode, and if those don't work, there's nothing we can do. In this case, since you have so little video memory set up by the BIOS, we filter out all the video modes that wouldn't fit, and the only thing that's left happens to be 640x480. Unfortunate, but the BIOS really won't let us do anything else.
Some machines have options in the BIOS setup to control how much video memory is allocated to the graphics chip at boot time. If yours does, that might make vesa work at larger than 640x480.
The invisible cursor bug on with the intel driver on 865 is already known and should be fixed for F11.
