Bad XOrg performance - RHEL 5/CentOS 5

I've noticed very poor performance with RHEL 5/CentOS 5. Mouse is choppy when moving. I've noticed that the mouse cursor will have a block of the desktop wallapaper covering it when moving sometimes. Also, mouse scrolling is very slow. Windows are difficult to move too.

Do you have Tools installed?

Yes, I do. They are running, I have confirmed this.

Weird, I just tried this and noticed the same behavior. You should definitely file a bug.

I installed using the rpm package. In my case, for some reason my xorg.conf was missing an entry for the mouse driver. I added
[code]
InputDevice "Configured Mouse"
InputDevice "XOrgMouseWorkaround"
[/code]
to the ServerLayout section and
[code]
Section "InputDevice"
Identifier "XOrgMouseWorkaround"
Driver "void"
EndSection

Section "InputDevice"
Identifier "Configured Mouse"
Driver "vmmouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ps/2"
Option "ZAxisMapping" "4 5"
Option "Emulate3Buttons" "true"
EndSection
[/code]
to the end (I got these from an Ubuntu install with tools, so they might not be tweaked the best for CentOS). Doing this solved the problem for me.

Thanks, I'll try this. I've also seen this same behavior (worse) in VMWare Workstation 6.

etung, thank you very much.

I was running RHEL 5 64bit ( 2.6.18-8.el5 #1 SMP Fri Jan 26 14:15:14 EST 2007 x86_64) in Fusion beta 4 and everything was wonderful - EXCEPT for the bizarre mouse behavior, which was bad enough to make it almost useless.

Searching the forum, I found this workaround, and it did the trick for RHEL 5 - I even cut & pasted the sections from your message into xorg.conf exactly as-is.

I noticed in another thread that you had mentioned that this workaround was in beta 4. If so, it apparently is not there for this environment - could it be that the vmware tools install takes a different path due to the x86_64 ? The tools install (actually, upgrade) behaved normally - I used the RPM installer.

In any case, thanks again - I can now use this VM.

I have no idea, can you verify this (clean install of RHEL5, install beta 4 tools, check xorg.conf) and file a bug if the fix isn't there? What version of xorg does RHEL5 use, 7.1/7.2/other?

Yes, I intended to do a new install anyway. The current VM I am working with was originally installed under beta 3, and then I installed the beta 3 vmware tools - (I didn't make a backup of the VM before installing the beta 3 tools). I will install clean and report the results.

What version of
xorg does RHEL5 use, 7.1/7.2/other?

It's 7.1.1 - here is a copy of the top and bottom of the Xorg log (after doing the patch):

X Window System Version 7.1.1
Release Date: 12 May 2006
X Protocol Version 11, Revision 0, Release 7.1.1
Build Operating System: Linux 2.6.9-34.ELsmp x86_64 Red Hat, Inc.
Current Operating System: Linux JBRHEL51 2.6.18-8.el5 #1 SMP Fri Jan 26 14:15:14 EST 2007 x86_64

I am using VMWare Workstation 6.0 and installed a CentOS 5 guest. After installing vmware-tools (rpm), I found that mouse pointer still does not "integrate" (float around the screen without doing Ctrl-Alt). Editing of /etc/X11/xconf.org according to your message above and the integrated mouse pointer works without issues.

Thanks for your tips. There is definitely something VMWare need to fix in future versions of vmware-tools installation process.
