maximum cpu load with -sharevts

[Michaël Witrant]

Xorg takes 100% of the CPU when it's run with -sharevts. Having another X server running or not doesn't change anything.

You'll need a remote access to reproduce and experiment this. Otherwise you may have to reboot very frequently.
* Log in remotely
* Kill any X server running
* Run "Xorg -sharevts &"
* Run "top" and check CPU usage

This patch fixes the problem.

[Michaël Witrant (mike-lepton)]

I've forgotten some version informations. I'm using Breezy and xorg 6.8.2-77.

Without the patch, the tty is closed when the server starts. I think this file is then scaned in a select or something, and probably raises an event continiously.
With the patch applied, the tty is closed when the server exits.

would it be possible to have the binaries of your xorg 6.8.2-77 with this patch already applied, I have the same issue here (on my slackware box with xorg 6.9) I would like to try this binarie to see if it resolve the issue... What is the version of Xorg you applied the patch in the first place? did it include the -sharevts option already or you had to apply another patch?

Many thanks.

You can get the binaries here : http://www.lepton.fr/misc/xserver-xorg-core_6.8.2-77_i386.deb
But I'm not sure this package will help you on your slackware.

The only patch applied is the one I submitted. Ubuntu team has already applied the sharevts patch (and many others).

I was able to modify source code from Xorg 6.9 and compile it under Slackware 10.2 CPU load seem to be resolve.... but sometimes 1 Xorg application will start to go 100% like crazy.... I'll try to dtermine what I'm doing for it to go 100% and I'll keep posting in this forum.

Can this bug be closed now?

[Michaël Witrant (mike-lepton)]

Probably. I don't know if it's been fixed or not, but it should be submitted to xorg team anyway.

Patch available for review

[Henrik Nilsen Omma (henrik)]

Setting the status to 'In Progress' since there is a patch in the works.

[Fabio Massimo Di Nitto (fabbione)]

The patch doesn't apply to xserver-xorg-core in dapper and the rediff doesn't solve the problem.

[Fabio Massimo Di Nitto (fabbione)]

ahh there it is..

[Fabio Massimo Di Nitto (fabbione)]

gone.... pkg uploaded in dapper, they will hit the archive in a few hours.
