1) Is this the right place for kernel internals questions and if not, what is? (Refresher: I am relatively new to Linux kernel internals, but not kernels in general. I've work on Unix and proprietary kernels, including my first seven years as a professional developing a whole system from the ground up.)
2) I noticed this morning that my GLMatrix screensaver is not working any more. I poked around and found a whole bunch of others that stopped working, including all the GLxxx screensavers. Any particular reason for this? The matrix one worked a couple of days ago even when I had to futz with the screen resolution and monitor resolution settings.
3) Now that I mention it, I'm still having trouble running the display configuration settings applet (it comes and asks for the root password, then disappears). What's up with that? This happens here at work and also at home....
4) With but one partition left to convert from NTFS to ext3, this one had to be the difficult one. It's my old C: partition from which I used to boot Windows. Three times now, with cp and tar, it has hung somewhere in the Documents and Settings directory and nothing brings it back. I managed to hang my whole system with a bad shell function, but the reboot brought everything back. I've gone to a directory-by-directory backup, excluding the D&S until tonight, but I was wondering if anyone knows why that one would be so difficult. I have no lack of disk space, so that's definitely not the problem. It stopped on one of the music player settings databases, slowing down at each one progressively until it hit the one that hung it, and these were hung for hours, so I'm pretty sure it wasn't just me being impatient. Probably OT....
Thanks.

Hail and well met, Mark
Is this the right place for kernel internals questions?
I have no idea...but I'll try to answer your questions anyway. If I get scolded, so be it.
I noticed this morning that my GLMatrix screensaver is notworking any more.
Open up a terminal window while X is running and type:
/usr/bin/glxinfo | grep direct
In a kind world, the response will be "direct rendering: Yes". If you don't get that response then possibly your driver is b0rked again or there's a problem in your /etc/X11/xorg.conf file. Perhaps you could run /usr/sbin/nvidia-xconfig.
Now that I mention it, I’m still having trouble running thedisplay configuration settings applet (it comes and asks for the root password, then disappears). What’s up with that? This happens here at work and also at home….
I think the command you can use in the terminal is /usr/sbin/nvidia-settings. It might give you an error report.
With but one partition left to convert from NTFS to ext3, thisone had to be the difficult one. It’s my old C: partition from which I used to boot Windows. Three times now, with cp and tar, it has hung somewhere in the Documents and Settings directory and nothing brings it back.
I got nothin'. :(
Give cpio a shot?
What's your tar command?
I've never attempted such a conversion.

There are Strange Things in various Windows directories that are a royal pain in the arse to copy for whatever reason. It's like they have locks or something, Windows system file-esque, that don't necessarily live in the root of c:. I've worked around this in the past painstakingly figuring out what can and can't be copied and scripting as I went.
It wasn't pretty.
Will.

Hail and well met, Mark
Greetings and salutations to you as well, honored sir!

I'll do that in another thread.

I'll try this when I get home and have a minute. FTR, here at work, where the screensavers work just fine, I get this:
[mhr@mhullrichter ~]$ glxinfo | grep direct Xlib: extension "XFree86-DRI" missing on display ":0.0". direct rendering: No OpenGL renderer string: Mesa GLX Indirect
(I also noticed that glxinfo is /usr/X11R6/bin/glxinfo....)

Again, later when I get home. Thanks.

Use "rsync -av /path/to/src /path/to/dest", that will allow you to 1) restart it and 2) --exclude stuff that causes you trouble.

Looks like a neat command (never heard of it before).
Unfortunately, I shot myself in the foot: after saving everything else, I forgot all about the D&S stuff and converted the partition. Good thing I have a relatively recent backup, but now I'll have to use it in the Windows under VMWare, and be VERY careful how I restore what (so as not to overwrite the new installation). Foo.
To backup all the other files, I wound up doing multiple tars, one for the files in the root directory and then one each for the directories in the root directory. I used 'find' and 'tar tvf' with some string manipulations to verify that I had, in fact, tarred up all the files. I even restored them in the extra space I found on the new /D partition, but see also above for foot problems. :-}
Thanks.
