Bug 430573

Could you please provide more info, e.g. output of mount and lspci commands?
Also please make sure the hal daemon is running. I suspect an invalid mount or
special kind of device blocking system (could be an USB connected device).

Also please make sure you have all Fedora 8 updates installed.

Fedora 10 on Dell D620, can confirm it happens as well - sometimes Gnome loads instantly, other times it takes 10-15 seconds to do anything - I can see only background and move the mouse, hard drive is not working (no green light flashing) - seems like is doing nothing then suddenly rapidly everything shows up.

I am using fusion-icon to start compiz-fusion effects (as default compiz does not include fusion efects) and I have removed from my session auto updating folder names or update buddy.

Fedora 10 on Dell Precision M4300 - just upgraded from Fedora 8 to Fedora 10 (fresh install) and it happens every time. Did couple of tests. Nothing is mounted (no dvd, no usb stick) and the delay is noticeable - about 20-40 seconds - even mouse animation is frozen during that time, then suddenly everything works fine.

Just found out that compiz is responsible for the "lag". When I enable compiz, it my computer hangs for 10-20 seconds at 100% CPU usage and is not responding, but after a while it works fine.

So when I disable compiz and restart my computer, profile loads almost instantly, when compiz is enabled, I have to wait 10-20 seconds.

And that only happens on one of my three machines, which is Dell precision m4300 with nvidia card, the other two (Dell Latitude d620 with nvidia on board and Dell Latitude 430 with intel) are not affected at all.

I can reproduce it everytime on Fedora 12.

Marek, what X.org driver do you use? Have you tried nouveau? There are known problems with binary nvidia drivers.

Also, running 'top' and sorting by CPU time would easily show you processes which have eaten CPU lately.

Thank you, nouveau is not an option as it does not provide any 3D support. Your statement is suggesting there is no problem with nouveau drivers, while in fact nouveau driver still has more problems than nvidia binary one - first of all it prevents nvidia drivers to be loaded correctly, then it does not support 3D acceleration at all. I support nouveau's development, but as for now it's unusable for me. My screen has resolution 1680x1050 pixels and I use external screen (1680x1050 too) and nouveau's performance is very poor, so even in 2D it's not usable.

Yep, Xorg jumps to 99%, then for 10-15 seconds there is no change to the screen (and all windows have no borders)... than suddenly everything is back to normal and Xorg uses 1-2% of CPU.

I must say, there is an improvement, in Fedora 10 it used to take up to 1 minute ;)

(In reply to comment #9)
> first of all it prevents nvidia drivers to be loaded correctly
Yes, that's correct, both drivers are binding the same device, you need to make sure only one of them is loaded at a time. For decent 2D performance with nouveau, you need nouveau drm kernel module to be active. Anyway, I'm not a xorg maintainer, just running nouveau on Quadro NVS 290 here and it works pretty nice.

That might be caused by a background fade together with a bug in nvidia drivers (especially when running multi-monitor configuration). I'm not aware of any option to turn fading off.

So, if you are sure this is caused by proprietary nvidia drivers and there's no issue somewhere else, please close this bug as WONTFIX.

bug 533620

Thanks Tomáš for these links, will read them.

Anyway, I do understand why Fedora cannot ship nvidia drivers, yet not sure why Fedora is ignoring their existence? My common sense tells me that Fedora should at least help nvidia to make their drivers work well. Nouveau driver is still not an option for many users and forcing them to use nouveau drivers and braking Xorg in the way nvidia drivers won't work properly... it really puts me off. I use Fedora at work and I don't really have time to play with nouveau drivers... and yes, since my upgrade to Fedora 12 I cannot use my second screen.

Thanks anyway.
