As far as i can see, this topic isn't solved till now. So i think, it is time to start a thread to solve this. Everyone is invited to give hints Facts i am pretty sure off: 1. ATI-drivers don't work accelerated on LM9.2 because the dri-library's got unresolved symbols 2. gatos-driver. I am not really sure, but i read, it is only for accelerated 3D, not 2D 3. actual XFree-CVS-snapshot. This has accelerated 2D, but is not stable and very hard to compile on Mandrake, don't know why. Perhaps Mandrake's got too many changes in standard-libraries? I don't know What i want from you is an answer to following questions: 1. Is there an easy and short way, to solve the unresolved symnbols from the driver? 2. An working step-by-step howto to compile a specific CVS-Snapshot on Mandrake or, even better, a ready2use RPM? 3. A way i didn't find out? The ideal result of this topic should be a working howto, i will rewrite then, for all modern, NOT WORKING Radeon-cards

It's definitely NOT the monitor-cable or DVI or something else peripherical. The driver in LM9.2 just isn't capable to use this hardware. Where i know? I got the same card furious3 The only way maybe are this gatos-thing above. The ATI-drivers are NOT sources, they fit only on a special version of XFree and a special OS. Didn't spend any further time in them, though. If you've got a faster solution, tell me B)

Ok, now i am on: du: "DiskUsage". Say you want to know how large some directory-structures are... this is it. eject/eject -t: To eject/load a cdrom. Defaults to the first one in alphabetical order. Else you add the /dev/hdX. ntop: same as top, but for network-traffic iptraf: The BEST tool i've found to monitor Network with menues in ncurse to select the wanted options grep: to filter output. A simple "cat /etc/services|grep -i http" will show you all ports concerning http. "|" : this tunnels output to another console-tool, like seen above. ps -ax: shows all processes with applicationname and pid, etc... /proc: You want to know everything about your smart machine like "sysinfo"? Here you are. For every information is a file which is readable (e.g. cpuinfo, filesystems, meminfo, modules, etc...) wget: wanna mirror a http/ftp-directory? "wget -r http://some-url.org/dummy/" will fetch all files in the path "/dummy" on "some-url.org" on your harddisk recursively. /dev/zero: wanna some zeros? Just copy this file to the file you want to fill with zeros. Be aware, it never stopps ;-) Nice way to delete a partition definetely. Just count the zeros with a for-loop until you filled all available bytes. /dev/null: this is a file where nothing is happening, it just eats everything. E.g.: "make bzImage >/dev/null" will copy every compiling-output of make to /dev/null, what means the screen keeps clean. route: shows all network-concerned routes/gateways For what do you need this all? Well, a small example: #!/bin/bash echo "Progress:" CPU=`cat /proc/cpuinfo|grep "model name"|cut -d":" -f2`; MHz=`cat /proc/cpuinfo|grep "MHz"|cut -d":" -f2`; cmdLine=`cat /proc/cmdline`; modules=`cat /proc/modules|cut -d " " -f1`; system=`cat /proc/version`; echo -n "#" echo "##############################">/var/log/sysinfo echo "#### System Informations #####">>/var/log/sysinfo echo "##############################">>/var/log/sysinfo echo >>/var/log/sysinfo echo -n "#" echo "1. You're system is a $CPU with $MHz MHz.">>/var/log/sysinfo echo >>/var/log/sysinfo echo -n "#" echo "2. You're commandline for boot was '$cmdLine'.">>/var/log/sysinfo echo >>/var/log/sysinfo echo -n "#" echo "3. You're OS is '$system'.">>/var/log/sysinfo echo >>/var/log/sysinfo echo >>/var/log/sysinfo echo -n "#" echo "Following all loaded modules with their options:">>/var/log/sysinfo echo -n "#" for module in $modules; do echo "Found Module '$module':">>/var/log/sysinfo modinfo $module >>/var/log/sysinfo echo >>/var/log/sysinfo echo -n "#" done echo echo "finished!" read -p "For results press a key." clear cat /var/log/sysinfo What you'll see is a progress-meter, after that the result. In /var/log/sysinfo is a file with the same contents. To be continued.....

Some Months ago, i tested many filesystems under LM9.1 and figured out the performance and CPU-impact. Look at My Webpage (No panic, it's english ;-)). Another thing is information in general. First of all, you have to seperate simple from professional filesystems. Under "simple" you will find: FAT: This is the primary Windows3.xx/95/98/ME/XP-Home filesystem, under NT/2k/XP there is additionally NTFS. It just seperates the space in blocks and every block is addressed. This makes it fast, but unreliable. There are no further security or backup-functionalities. It is very slow on huge partitions, what lead to users, thinking that they HAVE TO part their disk in thousands of partitions for performance reasons This filesystem is the reason for defragmentation-tools, because it puts the data on the disk without any logic behind. Just takes the biggest free block and that's it. ext2: This is the basic linux FS, similar to FAT but with unix-security-stamp. Because it is born under unix/linux, it is better using space on disk and of course, it is optimized for bigger partitions. On the other hand are professional FS. One VERY important feature is journalling, what means, that every action is packed in a transaction and this transactions are logged. So after an error, the system can restore the data according to the log. Another thing is handling of huge storage. Not every FS is capable to do this performant. Think of the CPU-usage. A complex FS needs a lot of management in the behind, so a small CPU will slow down the fs: NTFS: This Windows-FS has additional security-features, but is NOT journalling (or?). It takes about 10-20% of harddisk for a MFT-Block in which the disk is managed. It is much faster than fat, linux can only safely read it, writing support is pre-alpha. ext3: This is nothing really new. It is just a ext2 with an additional information-handling-routine for journalling. So you can use it even without ext3 support in kernel. After an error, it is very slow (20Gig, 7 minutes) in recovering. Because it is based on ext2, many users are using it. ReiserFS: This is an extraordinary FS. All Data is stored in a binary tree-modell, NOT concatenated in blocks. This makes it VERY performant on small files, what most files under linux are. For understanding, think of a pyramid of champagne glasses, one stands on two others, and you fill them from the top. That's simplified the way it works. If you understand that, you will notice, that it can't fragment, because it is based on fragmentation . It is relative fast in repairing, but no speed-wonder. All-in-All the perfect FS for small-filed partitions, like /etc, /home, /var, etc... XFS: This is new since about one year. It is a UNIX-based FS which is VERY professional. It has a whole bundle of extra features that are interesting for admins of storage-solutions. Rumours tell about it beeing very fast with huge files, i can't tell this, because it is as fast as ReiserFS as far as i can see. VERY good is repairing-time: it takes only seconds for my 20Gig-partition after an failure for restoring it. JFS: As professional as XFS, but i only tried it once and had problems (a year ago). Perhaps it is stable by now. Rumours tell that it is not stable by now, don't know further. Others: Many others are just for compatibility-reasons with unix-os. Be aware that with every OS you are using, you are enlarging the kernel and reducing resources. That's why i only use three FS (FAT for windows, ext2 for boot and XFS for the rest). Critics and additions are welcome

It's a possibility only available in BASH and Kornshell. If you've got a variable like $var, you can echo the filtered variable: echo ${var/...} Where ... is the content to be removed. There are lot's of additional possibilities, like remove all until end/begin of string depending on a sequence. Ex.: var = "Hallo du Freak!" var=`echo ${var/ Freak}` echo $var Leads to: "Hallo du!" One disadvantage is that this way is by far NOT so complex like sed or awk. Only simple things can be done like this...

Yes it does, too ;-) Found another now: echo ${var///}

I want to filter a variable for slashes: var=asdf/tzui echo ${var#/} Does not work, it filters only lines. So i have to find a way to filter the contents of a variable for / or and to change it in something else, p.e. a - var=asdf/tzui result=.........var../..-..... echo $result should lead into "asdf-tzui"...

There is a better terminalserver-wizard included, but i have no indept-experiences with it by now.

This thread should give advice if it is usefull to change a running 9.1-system to 9.2. So every post, indicating something new/better, beside of newer versions, is welcome ;-)

What means NW?

It's an IBM x225-server, LM9.1 installed. I changed the security level to a higher one and changed back again to standard. Now the whole machine is awfully slow, without any blocking process. What could that be??

I can't get X running clean, i get warnings and a black screen. I downgraded to LM9.0 for getting the drivers from via working, they install clean now. Someone did it?

:shock: Hä??

Ok, did it. Now my machine boots the default kernel, but mounts the root via initrd from my server. So my little ITX-Multimedia-PC is without any disks :-) The easiest way is to take a fat partitition and syslinux' it. Then install the kernel and all necessary modules in the initrd. Voilà (Not so easy to find in the initrd-things, but that's another story)

of course. My Kernel is SO individual, that the binaries wont work, although all v4l-things are there as modules, so the via-modules should find the interfaces to lock into. My kernel is only able to boot over network (NFS), doesn't know ANY filesystem except nfs, and so on. Means, it is stripped down for network-boot and nfs and v4l....

Want to take LM because of the ease of using URPMI... I did it now, bought a stick. Let's see how it does it's job...

get lots of unresolved symbols while modprobing them....

I am short before buying, to get a solution to boot lokal and remount root-fs from NFS after startup. So someone did it? Install LM on let us say 256MB memory-stick bootable? ------------------- PLEASE do NOT discuss about the WHY. I need the HOW ;-) If i am successfull i will bring up a little new howto :->

BUT...... You didn't build your own kernel and i HAVE to. Then it's impossible to use the provided drivers, because they are built for the default-kernel....

I want to build a kernel for my epia-Motherboard and need some not-standard kernel-features, can't use the default one. So i need to compile one. Because VIA only delivers prebuild binaries (modules) for their hardware, i am forced to build a kernel that can use them. Facts: 1. Theese modules are build for LM9.1-kernel (2.4.21) 2. I need to turn on "Root on nfs" because diskless client 3. I need them for X11 !! 4. It will get a multimediastation, if i can get it working Option: 1. Can someone give me a RPM for the BETA XFree86-4.3.99?? It has via-support... 2. I can't get it compiled, many things missing

Yes, i think i read it somewhere...

Is there an inside info, that tells me the date? I would like to use the new Terminalserver-drak-tool...

I found out, that watching TV will probably work. But what about the integrated MPEG2-Encoder, to record streams DIRECTLY in MPEG2-format?

Thx, the hint with the mcc dropdown was it. It's bad translated in german, so you don't know, that you'll find it there....

I use several remote RPM-sites as sources in URPMI. Because they are changing often, i want to see in a type of list, which of my installed RPMs needs/can be updated. Ex: Installed is SUPERKARAMBA v0.17 If i am trying "urpmi superkaramba" and the actual version is 0.24, urpmi doesn't recognize this. I have manually to "urpme" it, before i can "urpmi"ze it. Perfect would be a script or short-step-way to do a "update world". Any ideas?
