I'm having two rather odd problems. First, the more important one.
If I leave the computer for a while (say, 25-30 minutes), I return to a non-functioning KDE desktop. I can move the mouse cursor 'round (but not activate or click any menus, buttons, et cetera), and the keyboard seems dead. The only way for me is to "hard" reboot the computer. Now, this only started today, and I haven't changed an awful lot since yesterday. In fact, I've reverted most of my changes already (mostly in xorg.conf), but still it happens. The Xorg.0.log and syslog don't show anything unusual (to me, at least).
The second problem I also started experiencing today, after following Franklin's guide to
Making non-antialised fonts look nice. Everything worked, it seemed (I skipped the Freetype step as I had already upgraded it), but when I was going to take a look at my blog, Firefox crashed. I tried Franklin's suggestions of running Firefox from the command line, deleting settings, cache, even wiping out the entire .firefox directory, but without luck.
It also happens when I try to view the aRts web site (the only two I've had the problem so far).
Some version numbers for you to goggle at:
Slackware 10.0
Kernel 2.6.10
KDE 3.3.2
The latest NVIDIA drivers (6629, if memory serves)
Other than that, it's pretty much the original Slackware 10 release.
I'm dumbstruck.
Update on the Firefox crash issue:
I reckon it's got something to do with the fonts on my system (or lack, thereof?). After changing the theme of my blog I was able to load the page and it works just dandy. I'll have to look into it. The aRts page loads now, too (which confuses me, unless they've just changed something, too?), but as soon as I change the theme of my blog back, Firefox crashes.
Update on system hang problem:
Problem seems to be solved now. The xorg.conf I posted below is the same as after the changes I made (and hadn't tested at the time of posting). I changed the NvAGP option from 2 to 3 among other things, and so far everything looks good.
Update #2 on Firefox crash:
The problem's got something to do with Freetype 2 and the byte interpreter option, I reckon. I've also narrowed the crash down to sites using the font Helvetica. The funny thing is, Firefox is not the only browser that craps out; Galeon, Konqueror and Mozilla do, too. Perhaps it's a bug in Freetype? Or my Helvetica font is corrupted, somehow?
I reckon it's time for some further investigations...
Update #3 on Firefox crash:
Problem solved. I upgraded the entire X packages to slackware-current. Then I had some minor problems with starting up X 'cause the keyboard driver name had been changed from "keyboard" to "kbd" in xorg.conf (or was it the other way 'round? Ach!). Fonts looked terrible again, and I noticed the pkgtool hadn't removed the older x11 base package, either. So, I removed the old as well as the new x11 base packages, installed the new one, built Freetype (--prefix=/usr) and voilá! No problems anymore.
