[was Re: burning iso image on a Mac]

I'm just starting to play around with Linux. A couple of days ago, I
installed Ubuntu on my Inspiron 7500. When I switch from one
application to another by clicking (say) on a Firefox window when Help
is in the foreground, it takes many seconds before the newly selected
application is available and the screen properly refreshed. I'm
planning on installing Fedora. Is it likely to be any faster?


Thanks,
-J

I tried Ubuntu on my Inspiron 7500, but context switching was sooooo
slooooow it drove me crazy. Will Fedora be any swifter?

Thanks Patrick.




What exactly do you mean by context-switching? Between windows?
Between

desktops? Between virtual consoles? Between processes?

You're still top-posting. Please don't do that. It annoys a lot of
people on mailing lists including this one.

I doubt the problem you're seeing is related to Ubuntu specifically.
It's more likely a configuration problem e.g. with the X drivers, or
perhaps you're using Compiz and your video hardware isn't up to it. Or
maybe you have a slow machine with only a small amount of RAM.

You may have luck with Fedora, not because of the system but because the
default X setup happens to be different. If not, you'll still need to
tweak it.

It could be firefox specific...if he's running a firefox 3 prerelease or firefox 3 gold... There was an issue with firefox aggressively requesting a disk fsync to save state that appeared on linux late in the firefox 3 run up. Is this person running an affected firefox build on Ubuntu? I've no idea. In Fedora space this was addressed in an update package in F9. symptoms can appear as slow system response to the average user.* So... as long as a F9 install is imediately updated before using the
browser..or the install is done from the Unity respin that is
available..you won't see this particular problem.

For reference:
http://shaver.off.net/diary/2008/05/25/fsyncers-and-curveballs/


The reference is a good read.* I'm not saying this is the problem he's seeing... I'm just saying its a new sort of problem that cropped up recently. Generally speaking the video driver or acceleration issues you brought up are more likely to be the problem..especially if it still happens when firefox is not running. We'd need much more information from the original poster to be sure.

Good catch. I'd forgotten about that one.
