X zoom (ctrl+alt+plus/minus) keys and xvidtune don't work with radeon driver
Last modified: 2009-01-09 02:30:45 EST
Description of problem:
Using radeon driver for an ATI Radeon 9200SE, ctrl+alt+plus ctrl+alt+minus keys
do nothing. xvidtune -prev and xvidtune -next do nothing. Nothing in the log.
Only "xrandr --output DVI-0 --mode ..." works, but it is slow.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.get into KDE
2.press ctrl+alt+plus or ctrl+alt+minus
3.OR issue "xvidtune -next" or "xvidtune -prev"
Switch screen to next/previos video mode.
This worked in Fedora 7. Used same xorg.conf in both releases. Also tried some
changes to xorg.conf, but no effect.

log from FC7, where X zoom keys and xvidtune work correctly
Here's a log from Fedora 7. Everything works correctly here. This was
xorg-x11-drv-ati 6.6.3-4.fc7 .

xorg.conf which worked on FC7
This xorg.conf worked fine on Fedora 7. It is also the first xorg.conf which I
tried on Fedora 8. It does not work on FC8. In addition to zoom keys not
working, it produced a default max screen size of 2048x1200, whereas FC7

latest FC8 xorg.conf
Modified the previous xorg.conf to look like this, to try to resolve problems.
This fixed the part where it thought 2048x1200 was largest possible size. Does
not have any effect on the zoom problem, however.

FC8 log, after trying zoom keys, xvidtune, and finally xrandr
xrandr --output DVI-0 --mode 1280x1024
worked. Neither zoom keys nor xvidtune worked.

ATI Radeon 9200SE
GNOME 2.20.1 and KDE 3.5.8 (fails on both)
I have the same problem with fedora 7. Did it break on fedora 7 lately?
* Alt-Ctrl-+/0 does not work.
* xvidtune -next does not work.
* xrandr -s 640x480 does work.
I have needed stuff in /etc/X11/xorg.conf :
Viewport 0 0
Modes "1280x1024" "1024x768" "800x600" "640x480"
This is troublesome since some games use xvidtune method rather than xrandr method.

This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '8'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
