View 4 Replies View Relatedi have an old laptop (compaq armada m700... a piii with 576mb ram!!!) which i seldomly use. i have always "wished" i could use this old (and slow and crippled) laptop to do something basic, very basic: to connect to the internet, browse my email, maybe download and read a pdf, watch some stupid videos videos (-not in hd, of course i know!)... and that's about it (no gaming, no office, no photoshoping, no anything else!). but i wanted to do that in style: fast and without hazzle -as 'in having to navigate thru somehow obscure prompt commands or similar!'.
i've tried installing a bare tinyxp... but yet it takes forever to start up, load... and be ready to navigate. i've also looked at the linux world -albeit i am clueless on this os- and i tried installing different flavours of ubuntu and others. unfortunately results weren't much better than with tinyxp -in regards of starting up and responding to user interaction in a reasonably and timely manner. lately i've hear about the (in)famous chrome or chromium or whatever... but it seems it's not going to be ready for a while just yet and it won't necessarely work on such old laptops like mine
Everytime I log into Gnome Desktop I get this message :
failed to initialize a HAL context
Here is the exact error message when I look into auth.log

I'm on a Debian Linux system.
I am using a Fling KVM switch (by Belkin), to connect 2 computers to my monitor One computer is running XP and the other is running Linux. My wireless switching mechanism has just gone the way of the saints but Belkin has supplied a software solution for this occurrence. There is a small app called Fling (surprising) that allows me to switch from the XP machine to the Linux machine but nothing to switch back to the XP. What I need to know is there a similar app for the Linux computer. (NB I have tried Synergy but have no idea how to set it up - I've been told that synergy might work).

View 4 Replies View Relateddue to perpetual Mandriva worsening by the day I have recently took the plunge into Ubuntu. So far it seems perfect for me, my hardware is supported, I am getting a very pleasant desktop experience from it (so to say, the situation has reversed from 3 years ago when Mandriva 2008 was the better choice over the Ubuntu of those times).
However, it did not occur to me that Kbuntu was the KDE version I am now running Gnome Ubuntu. And hey, it is a nice Mac replica I would like to stay on Gnome! But! although I have mounted the old /home partition right onto its former /dev/sda5, Ubuntu Gnome would not allow me to log in with former Mandriva KDE user. The /home/my_old_user folder is still there...
Any way to keep my old KDE user in new distro on Gnome ? I am just guessing this would be the reason why Gnome does not see it - the old user account (because it comes from a KDE environment). Or ?
EDIT: I am now on kubuntu, and still can not access the old user account. How come ?
Is there a way I can change the security context of only the directories, & only files, recursively, in bash?

I'm linux newbie and I'm following a slackware-basics tutorial, I did as in the tutorial, but the configure stops and aborts:
Code:

What can I do? How can I enable/install selinux support? I guess it's related with AH and ESP protocols, which in my kernel are defined as modules (m). If so, how can I enable them?
I just get upgraded from F10 to F12. I am having problem with switching between users. The system would freeze up and the mouse would move unresponsively, could not restart system with Ctrl-Alt Del. When it freeze up, it doesn't give error anyway on next start.I suspect the problem is doing with Web browser, If one user using browser and switch to other user without logoff, it will freeze up when other using login.It seem working on following contion.
1. It seems ok when all users quit using browser,and it doesn't matter how many times you switch between users.
2. delete all other users and operate as only one user
I have OpenSuSe 11.2 64-bit installed on my HP Compaq 6730s laptop. When I'm trying to switch user black screen appears and my system does not react on any key combinations (ctrl+alt+del; ctrl+alt+F7 ...). This was not reproduced before ATI driver installation.
# uname -a
Linux xela 2.6.31.5-0.1-desktop #1 SMP PREEMPT 2009-10-26 15:49:03 +0100 x86_64 x86_64 x86_64 GNU/Linux
I readily admit I know next to nothing about Linux - so I am pleading mercy here.
My HP Mini 1000 had to be factory reset and that means no more Windows XP on the machine until I can figure out how to install it via USB flash. The machine comes with, from what I can figure out, a modified version of ubuntu.
What I wanted to do was to change away from this iphone-like default GUI but I cannot find any menu options to change the theme (System > Preferences > Theme) There is nothing like that anywhere on the computer as far as I can tell. Nothing. The OS help file even says to go to these menus, but they do not exist.
Does anyone have any knowledge that may be helpful here? Am I going to have to install a completely fresh OS? Surely there is a way to switch themes...
I am a Windows 7 user. I have two machines a laptop & a new bench top. Both machines run & boot Windows 7 very well. I use a very good program to clone my Hard Drive to an external USB drive. called Macrium Reflect. It is free and is a dream to use & very fast. This program creates a Linux based boot disk, which will allow you to find a backup clone file on an external drive to restore your hard drive. It works a treat on my laptop & has saved my bacon many times when I have messed things up fiddling with the registry etc.
The problem I am having is that my new desktop will not boot from the start up CD & returns the error kernel panic,not syncing cpu context corrupt. & then just tries to reboot again. I don't know what this problem relates to whether it is the computer hardware or the Linux CD or both. My laptop with the same OS does not have a problem, It is an Acer Aspire 5920G with 1.6ghz Intel dual core processor & 2gig Ram. The bench top has an Intel Dual core 3.3ghz processor, Zotac mother board & 4gig of Ram. both machines are running 32 bit OS.
I have browsed through the posts on this forum with people having the same error at boot, but as I am not using Linux & only using a boot CD I didn't think it appropriate to but into their threads. So I am hoping if some one can tell me is this a hardware issue or a Linux/New dual core CPU/ or Bios/Mother board issue. If it is a Linux issue then my Laptop surely would not boot would it? My bench top is only a week old and guaranteed, should I be sending it from Adelaide back to Sydney(purchased online from MWave) for fault inspection? or just take to a local Technician for a diagnosis. I am not having any hardware problem running Windows 7.
I have a primary language, Italian, and I want also use a secondary language, English. I want to switch language in order to have all the writings and messages in English not to write special characters by keyboard. I switched language in both kde system settings>Regional & language and in yast system>language leaving the keyboard layout Italian, but in the kde menu (the lizard on the left of panel) the groups of applications (multimedia, giochi, sistema) are in Italian and yast too (impostazioni amministratore), instead others are in English.
1)is this a bug or I forgot something?
2)which is the differences switching languages by yast and by kde system settings?
3)Is it possible to switch language and don't restart or logout the system?
One of our F14 machines was originally set-up with the i386 Kernel. I found out it had a kernel crash and the person tried to fix it by reinstalling the kernel, unfortunately they installed i686. Now some of our software that was setup to work with i386 is not cooperating. Is there a way to switch from the i686 kernel to i386 without reinstalling the system?

View 3 Replies View RelatedI'm running Ubuntu 10.10 and I'm running Skype 2.1 (Beta). Whenever I "x" out of the Skype program, from what I can tell it's minimizing the Skype program and not actually terminating the thread (just as it does in Windows), however when I "x" out of Skype the icon is not showing up in the system tray (but it does in Windows). So one would think that it's not running, however if I try to re-launch Skype I get an error message stating: Another Skype Instance May Exist.
I confirm this by going to System > Administration > System Monitor and sure enough, Skype is running. So if I "x" out of the program, how do I switch back to it because it's not showing up in the system tray? One last thing : Alt+Tab does not work. It will list the other programs running, but not Skype, despite the fact that it is running.
Found that RedHat Linux supports Context-Dependent Path Names in symbolic links using special reserved CDPN variables. Will it be possible to create a user-defined CDPN variable and use it in creating a symbolic link
