I tried to add my wife , and when I put in a password for her, this error comes up."Please set a valid user name consisting of a lower case letter followed by lower case letters and numbers." I did all that and I still can't set a password for her.

I do 'mkisofs -iso-level 1 -o image John Smith.txt'. Only an example. When I mount image, ls outputs john_smi.txt. So it has shorten to 8.3 and translated ' ' into '_'. This is in accordance with the manual, although it doesn't say the conversion will be done.

-iso-level level
.........................
With all iso9660 levels from 1..3, all filenames are restricted to upper case letters, numbers and the underscore (_).

However, as it did not reject the file name, it should have converted it to all upper case, it seems to me. And -iso-level 2|3 does the same thing.

I downloaded a source code package for an old multi-platform game. unfortunately, the author, when he created the .zip archive of the source code, zipped it in DOS, and so all of the file names are in all caps. when i run the configure script, it errors out, not being able to find any of the files (which originally were in lower case.
so, other than the extremely tedious process of renaming each file, one by one, is there any way to fix this so it will build properly? this game was written in 1996, so i don't think i'm the first person to bump into this problem.

Right, I seem to get very random system crashes. My machine will stay up for long periods of time, or sometimes only a few mins, also it doesn't seem related to just using a particular program. As you can imagine this is leading to a bag of woes. After reading on a forum about logs I went to /var/log and in the system log found the following entry . . .
"Jan 10 18:46:10 jon-desktop kernel: [ 92.718896] Either the lower file is not in a valid eCryptfs format, or the key could not be retrieved. Plaintext passthrough mode is not enabled; returning -EIO"
This is repeated multiple times and having checked after a few crashes seems to be the central problem. Being specific about the crashes, they freeze the entire system. Can't ctl-alt-del and sound loops, have to hard reset. I have a feeling that when I first installed Ubuntu 9.10 I selected to use an encrypted file system but have a feeling that I didn't set it up correctly. Not sure exactly what I didn't do but I seem to remember it was to do with generating a passphrase. So . . .
1) What is this error from my logs?
2) Is it linked to me not setting up the encrypted filesystem correctly?
3) Is there a way to check the settings / sort them out properly?
4) Is there documentation for my dullard state which can aid me in this, or is it quite simple?
Two files contain:
file1:
cat
dog
fish
hamster
file2:
cat
fish
ferret
dog
How do you change the case of the letters in file1.txt to uppercase and compare with file2 all in one command?
Is there any way to user can increase or lower his privileges? I tried by "semanage login" but it works only for admin i think. I would like for example change range form s0:c0 to s0:c0.c10 and vice versa.

I have made a simple bash script through which i can add, del, edit user from certain file using different CASE variables. like
case
1. adduser
2. del user
3. edit user
Now i want to add a exit CASE like
1. adduser
2. del user
3. edit user
4. exit
Now i want to make a script such a way that, if user input is 4 then only script quit. I used with exit function also but it didn't work. if user press ENTER or other keys then also it quit the program.

View 2 Replies View RelatedHow to lower the resolution of all the images in a pdf? I searched around and couldn't find an answer to this. I have a pdf file of a textbook that I use in school but each page is an image of 2 pages of the textbook (left page, right page when the book is opened) and each image is of a very high resolution. I downloaded pdftk and pdfedit but for such a simple problem, I'm having trouble. Is there any way to do this?
I have tried converting the 380 MB PDF file to PostScript but after an hour of doing that, it stopped, and the PostScript only had about 17 pages instead of the 733. So converting it back to a PDF file to utilize pdftk's algorithms would have been worthless. I know I could split up the pdf file into sections but I'd rather just scale down all the images, or make them mid quality PNGs or high quality JPGs just so the filesize can be halved.

View 1 Replies View RelatedI installed 10.04 1st by making a partition with bootcamp on MacOSX.Then I formatted the partition according to Ubuntu's instructions. I didn't install rEFIt, because I prefer to just hit the alt (option) key.I made the necessary adjustments according to URL...Community Ubuntu Documentation - and everything seemed to be working fine.I upgraded to Maverick and everything seemed to be working fine aswell.But then I noticed, that the wireless signal keeps failing and I'm asked to put the password again and again..
I don't think this is due to the upgrade from 10.04 to 10.10, but I just noticed it recently, maybe because of the air humidity, the signal was stronger a few days a go.. don't know!!Is there anything I can do?Perhaps install a new driver, or another wificlient, like Wifi-Radar??
I want to move notifications both from pidgin, rhythmbox and other apps to the lower right side so that they are not so intrusive, I don't know if it's possible.
View 1 Replies View RelatedI needed Ubuntu server and recklessly picked Karmic. Hardware is some regular 775 mobo with integrated Intel graphics. Monitor is ASUS VH222D. Installation went smoothly but after that problems occurred. Shell is displayed in 1920x1080 resolution and fonts are so small almost unreadable. Grub2 looks OK, standard non-fb and so does few rows of text after loading grub but soon after that framebuffer becomes active.
dpkg-reconfigure console-setup doesn't mention resolution. Some articles are leading to grub2 gfxmode but none of manuals helped. I just cannot change grub2 menu resolution to anything else than standard console fonts (non-fb). Kernel option vga=XXX is no longer working.How to lower shell resolution? Why is this automatic???
After upgrade to ubuntu 10.04 my screen resolution become 800x600 and in 'Monitors' I see only 2 options 800x600 and 640x480. but before upgrade I had much higher resolution in 9.04

View 3 Replies View RelatedI upgraded from 9.04 to 10.04.1 so I am still using legacy grub.Anyway, I noticed with the update that the console is using the framebuffer and using VESA for high resolutions.I really don't like or want this feature. So I added vga=0 to get 80x25 and it works initially but just when the X server is running (Xubuntu in my case) I can see how the console switches to a high resolution again. After this, if I go to a console, lets say tty1, it is using again a high resolution instead of 80x25 (VGA). Is there a way to force the consoles to be in a lower resolution and keep it that way? It used to work fine in ubuntu 8.xx and 9.xx
