Server :: Make Run Level 3 As Default Runlevel?
Mar 21, 2011I am trying to edit /etc/inittab so that I can make run level 3 as my default runlevel but whenever I try to edit it, it opens in read only mode. I am logging in as root still not be able to edit the file. It still shows read only. Also tried chown/chmod to change the file permission but it won't let me change anything related to inittab. Also checked the /boot/grub/grub.conf to see if the file system is mounting as ro. Also tried with rw but didn't work.

May 24, 2010I like to be able to type an em dash, so I set my right alt key to choose "third level" characters. This has worked fine until just now, I suddenly noticed it doesn't work anymore. I don't use it all the time, so I'm not sure when it stopped working, but I'm pretty sure it was working when I first clean-installed 10.04.
The last thing I installed was compizconfig-settings-manager, but after uninstalling that, it still didn't work. right now, when I press and hold right alt, it's as if the key isn't being pressed, every other key works as if nothing is pressed, whereas if I press and hold left alt, it acts like an alt key.
Ubuntu :: Compose Key And Third Level Key - Don't Work On 10.10?
Apr 3, 2011I was trying to follow instructions from here [URL]..community/ComposeKey but couldn't get ANYTHING to work and can't type any special character. According to the instructions, if no third level / compose key is selected, then AltGr switches to third level and Shift+AltGr to forth. So I leave them unchecked to get default behaviour and they trying to type something but no characters appear.
I then started to experiment with different checkboxes, setting third level to Menu and Right Alt, combining them with checkboxes in Compose key position group - with no success. Any ideas what is wrong with this?

View 1 Replies View RelatedGeneral :: 1:1 - What's Meant By There Is Kernel Level Thread For Each Pthread Created
Mar 11, 2011I have gone thorugh some documents about pthread (NTPL ) in linux 2.6 kernel. As per that linux uses 1: 1 threading model and for each user level thread there is kernel level thread. Pthread_create uses clone system call to create a LWP and the kernel could treat that as a LWP and do scheduling and all .( different from linuxthread). My question is what's meant by there is kernel level thread for each pthread created. Can I see the kernel level thread if I call pthread_create using ps .
What exactly meant by 1:1 .I mean for each user level thread there is kernel level thread . If I make a system call from a thread does the OS services that action via kernel thread ( created using kernel_thread () or some other way ) internally ..

Jan 20, 2011We all know linux kernel base layer is made up of structures, in which every object of kernel is well defined. Structure members correspond to object properties required to define object behavior.
For example if we take case of File system.It composed of four objects , superblock objects, inode objects, file objects and dentry object.Each having well defined structure which is being operated by system call handler and by system call service routine in the kernel mode.
Now my question is even in kernel mode we do not have some mechanism by which we can get access to pointer of these structures.We have some macro.
If I want to manipulate structure on my on way, or performing some more operation defined by me.For example after the crash of Hard Disk Drive, having ext2/3 file system, If i want to know all the inode pointers, and block details.
Can I have some way out to do desired operation ??
mechanism to operate on these base label structures, even in kernel mode ..

View 2 Replies View RelatedOpenSUSE :: Move Transparently Between Run Level 3 And Run Level 5 As Autologin User?
Aug 10, 2010I've been able to kludge a kill script which finds the correct pid for the kdeserver (or gnome server) after my system comes up in run level 5 so I can drop back to run level 3 mode. Lots of experimentation showed me that using telinit 3 and telinit 5 would occasionally leave the video memory in a mess and I would have the black screen of death.
I set the security parameter setting to autologin for me since I am the only user of my machine, but I still have to kludge the default setting under sysconfig (the DEFAULT_WM) under Window Manager to pick a certain window manager, so it takes time to manually switch the desktop.
Right now I can leave the gui and drop back to cli, but painful experimenting showed me that killing the X server is a no no. Right now I kill the kde server, which sends the SIGTERM to the X windows manager, which then figures out that it has to shut down.
Questions: Is there a better way of doing this? Apparently openSUSE figures that we have multiple users logging into the gui desktop, so the gui is always kept running and a login window with the desktop manager option forces the user to login in. With autologin, this never happens, but no choice of desktop is possible on the fly.
Can some type of script be set up to painlessly enable this to happen? And what is the best way of bringing either the Gnome or KDE desktop manager down gracefully? I do get lots of error messages as the system attempts to recover and X shuts down. It appears that apparently the single user with autologin is left out in the cold.

Apr 14, 2011I've been using Eclipse PDT with Zend Debugger to debug my PHP web scripts for a while, but after installing Ubuntu 10.04, I've been having issues setting up the development environment again.

Eclipse was installed from the Synaptic Package Manager. I installed the Zend debugger and PDT for Eclipse under Eclipse's Help -> Install New Software.
Yet whenever I try to debug a web script it executes the script without stopping at any of my breakpoints. The debug window immediately shows the debug session terminated.

Ubuntu :: Unable To Get The Debugger Gui, Kdbg In The Repositories?
May 6, 2011I just installed 11.04 and found that the debugger gui, kdbg, is no longer in the repositories. I have all repos enabled except backports. I also tried to find any information about the fate of kdbg, whether it is just not yet packaged for 11.04, or whether it is discontinued, but to no avail.
If it is being discontinued, I'll probably roll my own .deb package and post it somewhere - kdbg is too good to drop, I think. And while we are at it?

OpenSUSE :: Debugger Exits Without Stopping At Breakpoints?
Sep 14, 2010openSUSE 11.1
KDevelop 3.5.5 using KDE 3.5.10 "release 21.12.1"
gdb 6.8.50.
Problem: When I attempt to debug my program with breakpoints set the debugger does not stop at breakpoint. Message in gdb window is:
/bin/sh -c libtool gdb .../C++/Graphyxs/debug/./src/graphyxs --interpreter=mi2 -quiet
(gdb) set print static-members off
(gdb) Process exited
Attempted fix: Some forum posts suggest KDevelop upgrade. Upgraded from 3.5.4 to 3.5.5; gdb upgrade not available in openSUSE.
Other posts recommend assurance that debugger options are properly set. KDevelop Project Options has Compiler Flags -O0 -g3 with "debug" configuration.
Ubuntu Installation :: ATI Driver And New Kernel 2.6.35 Kernel - No Longer Work
Nov 24, 2010With the recent upgrade kernel, my ATI driver can no longer work. After upgrading to the new kernel, upon reboot I would get stuck at the "checking battery status" and can't boot into kubuntu.
I'm running Kubuntu 10.10 64 on intel i5 with radeon hd 4870.
So I thought I messed something up since I was fooling around with conky script the day before. I did a clean install of kubuntu 10.10 64 and reset all my settings and my files. At this point, everything works smoothly and I can reboot multiple times without a problem.
I proceeded to install the Radeon catalyst driver following the documentation, which worked perfectly for me on the previous kernel. After rebooting, I can no longer get pass the "checking battery state" black screen. I had to boot into safe book, uninstall all fglrx and also delete xorg.conf to be able to boot back in normally.
