I have a few KDE apps that I like using for various tasks. Unfortunately the interface fonts were messed up so I installed the KDE base to get them working again. KDE has now hijacked my system and is using all of its apps instead of the ones /I/ want. The current problem is that Mozilla-Firebird is no longer my default browser. Any idea of where to fix this? I tried kcontrol but I couldn't find anything that would allow me to set the default applications... thanks :) emma PS I'm using openbox as my WM, /not/ KDE. -- Emma Jane Hogbin [[ 416 417 2868 ][ www.xtrinsic.com ]] -- The Toronto Linux Users Group.

Compiling the 2.6 kernel

Just make sure to compile in IDE if you're booting off an IDE drive, or all the necessary scsi stuff for that. Basically, initrd is a sort of in-memory filesystem for the kernel to be able to load modules before it has mounted a filesystem. This is used in distributor kernels so they can make all drivers, including IDE and SCSI, into modules, and then probe and load only the required ones at boot time. They can't get the IDE module from an IDE disk, because the kernel doesn't know about IDE, because the IDE driver is in the module... Otherwise they'd have to compile everything in, making huge kernels and wasting lots of memory. Here's the really easy way to get 2.6 running on Debian: 1. update to unstable 2. install module-init-tools 3. get 2.6 source 4. configure 2.6, making sure to build in anything you need to boot (e.g. IDE, text console) 5. use make-kpkg to compile the kernel and build a Debian package of it 6. install said package 7. reboot and enjoy This will take care of all version dependencies. The new kernel is so much smoother than 2.4 even with the CK interactivity patches. If you're using the nvidia binary driver, there's a shortcut you can use to getting those up and working, especially with the Debian package management system. 1. Use the Debian packages to get the driver up and running with a 2.4 kernel, specifying "no TLS" when asked. 2. Reboot into 2.6 3. Get the 4496 patch and installation instructions from minion.de. 3. Apply the patch into /usr/src/modules/nvidia-kernel/nv/ and build according to the minion.de instructions. You might have to manually copy the resulting nvidia.ko driver into /lib/modules/2.6.0/kernel/drivers/video/ , I don't remember. 4. dpkg-reconfigure nvidia-glx, and say "yes TLS". You want to do this because the debian packages handle all the necessary diversions of GL libraries and general package administration, so nothing will break the next time you update X or mesa.

Problems with KLaptop
by linuxbrad-bJEeYj9oJeDQT0dZR+AlfA＠public.gmane.org 29 Dec '03

29 Dec '03

I'm running Mandrake 9.2 on a Compaq Armada E500 laptop. When I first installed the system, KLaptop would helpfully warn me when the batteries was low. Recently, I've run into the problem where the Klaptop monitor says I still have 40% on the battery but then the laptop suddenly powers off as if the battery is dead. Is there a way to fix this? The battery seems to last the same length of time as before, it's just that KLaptop seems to have an inaccurate measure of remaining battery life.

I do have an identical spare drive but how can I make an exact copy of a drive with a messed up file system and also, how can I be sure that the copy is non-destructive? If I can do this, it'd be wonderful! Madison PS - I got a dd of th last tape that ran (finally) and it is about 3.6GB (about right). I extracted it as a tar.gz (which should work) but it fails claiming to not be a gzip archive... Any ideas on that front by chance? > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Hi Madison, > > First, if you have a spare hard drive, make a copy of the data on the > bad disk (or better yet two) in case the hardware will die, and work on > the copy. > > Then do: > > # /sbin/mke2fs -n /dev/hda5 -b [blocksize] > Be sure to use the right block size here! > > You will see output including: > > Superblock backups stored on blocks: > 8193, 24577, 40961, 57345, 73729 > These are the locations of the superblocks. > > Pass these one by one to: > > e2fsck -b [backup superblock location] -y /dev/hda5 > > [read up on "man e2fsck"] > > If one of these superblocks are OK, e2fsck will start recovering all > possible data (the -y switch means "yes to all"; otherwise you get > thousands of prompts). > > All the possible files will be dumped into the /lost+found directory. > - From there, you should be able to do something like: > > find /lost+found/* -name [some directory you are sure of the location of] > > i.e. > find /long+found/* -name anton > allowed me to find my home directory. > > the /lost+found directory basicly contains many hard links to the same > files. > > You should be able to find your /home, /var, /etc, or whatever other > directories you have on the drive and move them back to their respective > spot. > > Be careful - many files may be corrupt without warning. > > > Using this technique, I was able to recover an ext3 partition after > deleting it, resizing the partition, reformatting as reiserfs, and using > it for two days.

Have you tried using debugfs (part of e2fsprogs)? It lets you tinker with the superblock manually. Also: happy birthday.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Madison, First, if you have a spare hard drive, make a copy of the data on the bad disk (or better yet two) in case the hardware will die, and work on the copy. Then do: # /sbin/mke2fs -n /dev/hda5 -b [blocksize] Be sure to use the right block size here! You will see output including: Superblock backups stored on blocks: 8193, 24577, 40961, 57345, 73729 These are the locations of the superblocks. Pass these one by one to: e2fsck -b [backup superblock location] -y /dev/hda5 [read up on "man e2fsck"] If one of these superblocks are OK, e2fsck will start recovering all possible data (the -y switch means "yes to all"; otherwise you get thousands of prompts). All the possible files will be dumped into the /lost+found directory. - From there, you should be able to do something like: find /lost+found/* -name [some directory you are sure of the location of] i.e. find /long+found/* -name anton allowed me to find my home directory. the /lost+found directory basicly contains many hard links to the same files. You should be able to find your /home, /var, /etc, or whatever other directories you have on the drive and move them back to their respective spot. Be careful - many files may be corrupt without warning. Using this technique, I was able to recover an ext3 partition after deleting it, resizing the partition, reformatting as reiserfs, and using it for two days. About 70% of the files got recovered, but it obviously depends on the damage done. Madison Kelly wrote: > That would seem to be the case.

[module pwcx.o]
by mr6re9-mI4xJ4qlgtBiLUuM0BA3LQ＠public.gmane.org 29 Dec '03

29 Dec '03

This is a so called "OPTIONAL" plugin to the pwc driver my system chose to load for the Logitech QuickCam. I added it in to hopefully unlock some useful features of the device. In particular, I didn't like the tiny 160x120 images. I understand that by default there were insufficient buffers available for larger captures. pwc and pwcx reference http://www.smcc.demon.nl/webcam/release.html The method I chose to get the larger captures was quick-n-dirty I know, but I'm not all that familiar with rebuilding kernels. The problem is RedHat's versioning. This "OPTIONAL" plugin is NOT available as source and so the alternatives are to fall back to a clean 2.4.20 kernel or go forward to 2.5 or 2.6. In any event, insmod --force pwcx does the trick for now. Another nagging problem is the way this device causes the sound card config to be overwritten at times. It shows up as 5 new sound devices on a reboot and if configured then, will become the only sound device available as a microphone. And the mic don't work either. I can restore the sound server by rebooting with the cam unplugged. There are other ways but I'm in quick-n-dirty mode right now. I believe I can fix the multiple sound card problem with ALSA, I seen something in the errors about full duplex. So I guess what I'm asking is this: Can I avoid another 18Mb syslog thrash with any more quick-n-dirty tricks? or Have I reached the work-around limit for this device and need to build that custom kernel? farmer6re9 -- Eating Crow is better with MyCrowSauce -- The Toronto Linux Users Group.
