Red Hat Bugzilla – Bug 588095
most modes not used because default hsync/vrefresh range is too small
Last modified: 2011-06-27 12:02:19 EDT
Description of problem:
When using the "vmware" graphics card "emulation" in KVM, the Xorg server in Fedora 13 uses a resolution of just 800x600 (whereas the X server on the host is running at 2048x1152) because most modes are rejected with either "vrefresh out of range" or "bad mode clock/interlace/doublescan". This is caused by using the default hsync and vrefresh ranges of 31.5-37.9 kHz resp. 50-70 Hz.
Explicitly configuring the hsync / vrefresh ranges in xorg.conf works around the issue.
xorg-x11-drv-vmware should probably report a fake connected monitor with wide hsync / vrefresh ranges.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. kvm -vga vmware -hda ...
2. (inside kvm) startx
Screen is upscaled and blurry because of low resolution in guest. Also screen updates take several seconds (!).
Sharp image, almost instant screen updates by running at a resolution matching the KVM window size.
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13. 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bug reports from releases that are no longer maintained.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 '13'.
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 13'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 13 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 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 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no longer maintained, which means that it will not receive any further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.
