Is this a widespread problem? I can't find similar questions asked so it may not be.

I use Image Viewer to sort all my photos. It was fine all the time I had 10.04, but now with 12.04 after an indeterminate number of file openings it kind-of-freezes for a while. Sometimes seconds, sometimes minutes. All the while it's stuck, any music in playback will continue to the end of the track, then stop; and while the mouse moves it's glitchy and if you click on anything nothing happens until it un-freezes.

I've had the system monitor running while this happened, and all resource usage was low (including memory and swap-partition- memory ~10% and 0 use of swap).

The data I'm accessing is on a separate partition to OS, but that's common so I doubt relevant.

I'm running a default GFx driver until I can work out how to make the proper one for my system work, however surely it wouldn't be that? No other applications seem to cause the same problem, including editing images in GIMP which I'd have thought would exercise the same GFx elements plus more.

One thing I have noticed is it seems to occur more regularly in more elaborate front-ends. So it's been worst in full Unity, and probably least bad in Gnome Classic and LXDE. But that could be coincidence (or mis-remembering on my part?!)

For info I'm running an Intel Core2 Duo E4500 2.20GHz with 3GB RAM.

As nothing crashes (app or system) I'm not sure any log files would be of use? Happy to inspect & post results up if there are any that might be useful in this case.

So... any ideas what could be the probem?

What gfx card and default driver? –  izx May 21 '12 at 3:38
    
I recommend trying Viewnior. I've never found a more awesomely awesome image viewer. On my desktop, loads images in less than a second (granted I have 8GB RAM and an SSD, but still...runs faster than any other image viewer I've tried). Only two dependencies...libgtk2.0-dev and intltool make sure you have those installed. Then grab the tarball from the download page and install xsisqox.github.com/Viewnior/download.html –  titaniumtux May 21 '12 at 5:04

GFx- it's an motherboard-integrated Intel chipset on a Dell Vostro 400. I think it's a 945G, one of that family anyway; either way I believe the xf86 intel driver is supposed to be the thing I need. Viewnoir- ok I'll give that a shot sometime soon. Bug- yep, fair point. Still trying things to at least work around it, when I'm a bit further along I'll post it up. –  Mark Whitehead May 21 '12 at 20:17
    
This question should instead be filed as a bug report, and as such is off-topic, thanks! Instructions on filing a bug report are here. –  fossfreedom May 21 '12 at 21:36
