I have a longstanding problem with Knoppix, which does not boot in my HCL laptop. I have tried versions from 5.0.1 to 7.0.4, but none can boot, either from CD/DVD or from hard drive using grub&cheatcode.
I don't know where it gets stuck.
Sure, a log file can tell.
But how to read that log file when the system can't boot? Can these operations be performed in a virtual machine, and is it then possible to read the log file?
This, I hope, is an interesting question, and I hope, will interest many.
You can try "boot: knoppix vga=0 debug -b 3" from Cannot boot
I will try this and get back ASAP! Thank you for your prompt suggestion, as always.Quote:

I should have written exactly where the script stops. Then the time wasted in above messages would have been saved. I am sorry. The script stops at init 5, just after displaying the Tux in Vitruvian pose. init 6 works, and shuts down the system.Quote:

Ok, try "boot: knoppix vga=0 debug -b 3" once more. You'll see messages

/KNOPPIX-DATA
/UNIONFS
symlinks to UNIONFS
Final DEBUG Shell before starting init
At this point type
to enable logging in '/var/log/'. (Caution: us-keyboard!) Proceed withCode:mv /etc/syslog-knoppix.conf /etc/syslog-knoppix.orig
exit => Control D => init 5
Your Knoppix doesn't go on; therefore change with "Strg Alt F2" to the terminal and examine the logs at '/var/log/'. Perhaps you can find what is wrong with starting the GUI.
In case of HD Install: Don't forget to rename '/etc/syslog-knoppix.orig' to ' /etc/syslog-knoppix.conf'; otherwise your persistent memory has no more free space soon afterwards.
Which of the log files? there are two, xorg.0.log and pm-powersave.log!Quote:
examine the logs at '/var/log/'.
It should not be xorg.0.log, since graphics is displayed alright! The console kit folder has one file that is readable.
The cups folder has 3 files that are readable.
The rest folders are empty.
I will nevertheless read them and get back. Please bear with me. Thanks/
Greetings, rajibando.
In Werner's post #6, the mv operation must be done as root to be effective.
Likewise, later you must restore the file as root.
If you issue the mv as knoppix and not as root, nothing happens.
The purpose of the original /etc/syslog-knoppix.conf is to disable most of
/var/log/ including syslog. Werner's post #6 tells us how to re-enable full
/var/log/ capability temporarily.
I expect /var/log/syslog may be what you want.
Dear Mr.Schulz,
I have attached the zipped file for Xorg.0.log.
http://knoppix.net/forum/attachment....1&d=1360772976
I hope you could find something there that would be of some help.
Maybe Nouveau driver is creating some problem?!
And greetings, Mr.Utu,
There is no file named /var/log/syslog
Thank you.
Are there not "messages" and "syslog"? Besides I have daemon.log and kern.log.
Within the final DEBUG shell you are root; type "whoami" to verify it.Quote:

None! What do I do next?Quote:

There are two files: one is what we renamed as .orig and the other being syslog.conf . Do you want me to rename the syslog.conf file like we did for the file syslog-knoppix.conf?Quote:

Can you see the wallpaper after "Tux in Vitruvian pose" or what happens otherwise?Quote:

Tux remains in the pose forever! But alt+Ctrl+F2 takes me to the console.Quote:

I've looked over your Xorg.log.0, but I'm not expert for graphic card problems; perhaps this may help:
Video-detection-wrong-resolution
I didn't believe the video would be the culprit once again. I had cracked this once in Debian Lenny. Since my desktop had no problem with nvidia card with the Knoppix DVD, I did not assume my laptop, which also has an nvidia card, will have a problem with the same DVD.Quote:

Thanks.
But this setup is bare-minimal and does not have the snazzy effects of compiz fusion plugin.
What I find is that the concerned graphics cards' chipsets are different. Perhaps this is why Knoppix can't boot into graphical display.
Maybe future versions will, I hope!
Well, it seems that you haven't tried the obvious "future version", 7.0.5. That might help. already. But Nvidia on Linux seems to be an eternal source of pain - personally, I have several laptops with dual graphical systems, and I often fall back on the simpler, integrated version.Quote:
Maybe future versions will, I hope!
One last resort is of course to download Nvidia's driver:
http://www.nvidia.com/object/linux_display_ia32_190.42
But .deb packages could also be available, they are definitey for Ubuntu.
What do you mean by this? Does your laptop have two cards, or you have two GUI-operating systems installed on a laptop?Quote:

Which it doesn't seem like you have done.
This kind of reasoning is, IMHO, just to ask for problems when you use Nvidia.Quote:

I thank you for the information. Actually, this option was earlier available to desktops with add-on cards.
I recall that my circle of ignorance is infinitely larger than my circle of knowledge!
On this note I would like to end this thread.
Thank you once again!
