I am using grub of version 2, and current resolution vga=795 (probably). X runs at 1680x1050. So what I would like to know is, how can I count the right VGA parameter number for grub, to use another resolution?

View 2 Replies View RelatedI am a noob and I am trying to display a count of the number of subdirectories in a directory. I have been able to use find -type d to list directories and subdirs but I want a numerical value of dirs and subdirs. I know ls -l gives a count but when I try ls -l -d all it shows is "." I also have tried a combination with the -R option but nothing seems to be working for me.Please forgive my ignorance but I am working on a script for class and this is the first step.

View 4 Replies View RelatedI am trying to do a fsck on my ext3 partition, but so far failed to let the system come up in single user mode and having the partition mounted read only. It says in the kernel parameter that it is read only (RO) but still mounts it RW. A remount with mount -o remount,ro does not work, since / is always busy. what to do to get a fsck done? I don't want to boot into a rescue system, this should be possible on a running system (like Windows does it, when rebooting)

I'm trying to find a script that will return me the largest number of repeating characters. Say, I have the following line in a text file: 12345AAAAA6789AAA
I want it to return 5, because "A" is repeated 5 times in this line (more than 3 at the end).

I'm the POC for all my families Linux computers. Is it possible to get statistics on which programs are accessed, how frequently, for how long and by which user?
When it comes time to upgrade it would be useful so I know which programs to concentrate my testing. I usually just e-mail and ask but every time people forget to send me the programs they actually use.
I am trying to get the count of number of CD-ROMs attached with my Linux system using a bash shell script. I have decided to use the following method for it:
Code:
debian:~# cat /proc/sys/dev/cdrom/info | grep "drive name:"
drive name: sr0 hdb
So basically I know that there are two CD-ROMs attached to the system. Now there can be three also like this:
Code:
debian:~# cat /proc/sys/dev/cdrom/info | grep "drive name:"
drive name: sr0 sr1 hdb
All I want to do is in my shell script to get the count of the devices in a variable using the above command.
Let's start with some context: About a week ago, I saw in the university computer that the text mode consoles(ctrl+alt+f[n]) worked with a great resolution on a 19" wide screen (I think it is 1440x900) running fedora 11. So I wondered if I could make the text consoles at home to work with a good resolution also.So I started to search for that and found the kernel parameter vga= . The problem: it doesn't support 1440x900 or any other 16:10 resolution for my graphic card. Then I thought that maybe fedora uses some module that allows that, because the livecd allows a good resolution (by default) on my desktop computer.
What I thought so far is that fedora is not using vesa for the virtual console (which i think is the driver that ubuntu uses) and I want to know what driver it is and how to use it in ubuntu (either compiling the kernel or simply installing something).I don't even know if my guesses are right or not. But I've gathered some info so far:From /var/log/messages (fedora 12 livecd) I got this part, which I think is the really interesting one.Quote:

I am using 10.4 ubuntu and it shows next a white ubuntu symbol. It then starts doing a system scan and gives a percentage when it gets to 33% it stops and says it can't mountall and that there is something wrong with the file system I can't get past this unless I don't even let the scan start. I think something is a file is messed up but I have no idea what to do.
View 3 Replies View RelatedI've compiled and added a kernel in Gentoo before. It doesn't seem to go quite as smoothly in Kubuntu 9.10 These are the steps I followed: I unpacked the kernel in /usr/src and ran make && make modules_install succesfully. Then I copied the kernel in arch/x86/boot/bzImage to /boot/bzImage-2.6.32 This entry is the one given by Kubuntu:
Code:

On the boot up to the Grub loader screen my monitor (Acer X193w) displays a "screen resolution not supported" message in a floating window, even though the Grub screen itself is displayed. It appears as a flattened rectangle, like wide screen format films on a TV (black bar top and bottom), the floating message on top of it. Once Debian is selected and boots, obviously my xorg.conf takes over and sets the 1440X900 resolution and everything is fine. But the Grub start up bothers me. How do I set the resolution of the Grub loader screen?
