Hardware Profile

Sorry in advance for the story wanted to give as much detail as possible.  As I don't think this is a gnome specific bug but something gnome is using.


I was running Fedora 14 with a Nvidia 6200 card NV40 I think.   I was using the proprietary drivers.   Using a game Heli-X I would notice that I got about 5 fps if I was lucky.   Using compiz or gnome-shell it was rather sluggish.  If I was playing a video via mplayer or other player it was a little choppy but workable.  But if I moved a window, or had some text scrolling in a terminal window forget it.  I had skipping and pausing of windows all over the place.  gtkperf took about 1.5 minutes as well.

I thought the this was a hardware issue as the same desktop ran fine on my D620 Dell Laptop (intel card).  The Computer with the problem is a quad core xeon so you'd think would work faster than the laptop.

Recently I got a "RV710 [Radeon HD 4350]".   Using the proprietary drivers from ati/amd I would get about 60 fps in openbox/metacity and about 40 fps using compiz.  But the desktop was still sluggish moving windows around and same problem with playing video. gtkperf took about 40-50 seconds.  Eventually my system crashed due to my fiddling I decided to wipe the system and put a fresh rawhide F15 to see if the new gnome worked any better.

In Gnome 3, same sluggishness.  (I'm now using the drivers that came standard with the install)  It took anywhere from 3-10 seconds to bring up the activity menu.   Things seem to get worse if I had a vnc or rdesktop session open.  They could even be minimized, and on their own virtual desktop and it was still really sluggish.  Actually I hate the big bars in gnome 3... I feel so much space is wasted in the new gnome 3, so that led me to check out the new kde.

In the new kde things seem a little sluggish but at least 4 times faster, in my opinion, to gnome.  Also if your moving a window around it doesn't seem to effect the speed of other windows on the desktop.   I enabled the 3d/compiz effects and I've had a HD movie playing in the background.   And was able to work.  The video would do some wonky things while I was moving windows around, like skipping frames, but the video stayed in sync.   kde seems to work way better on this system.

What do you need from me to further troubleshoot this issue?

I've tried switching to KDE to see if there's much difference.  KDE is much faster and since I can bring up FPS I can see what's going on.

In KDE the OpenGL seems to be the slowest.  If I open rdesktop in either KDE or Gnome (gnome actually being worse) it slows the entire system to a crawl.

If I switch to xrender system performance seems to be much better.

Just an update to this.  I've applied all the latest updates in Fedora 15 rawhide.

When first logged in, everything works great.  But as I start opening/closing applications the performance get's really really sluggish.

More updates on this:

When I deactivated the bridge and used Network Manager.  This seems to speed things up but after an hour or so of usage the 200 ms to activate the Overview page turns into 2-10 seconds.

At that point even closing all applications it still will take over 2 seconds.  Only way to recover is to log out and back in.

More updates on this issue:

I've been working now for 4 hours with no problem.  Only thing I changed, I unplugged my second monitor.   

This issue only seems to happen when there's a second monitor attached.

Comment 6 Fedora End Of Life 2012-08-07 18:16:47 UTC
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached 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, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

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:
