Linux and the hungry Penguin

Receiving remote X connections

Hi,

I use several Linux boxes and I like to open applications on remote boxes and have them displayed on my local Linux machine.

By default openSUSE 10.2 disables this functionality and remote X connections are not allowed. Every time I install or upgrade I need to reconfigure this option and I keep forgetting how to do it. So this time, after search the web for the answer, I thought I would blog about it so that I know where to look next time!!!

By default the X server is started with "-nolisten tcp" which stops remote X clients connecting to the machine. This ability to make remote applications display on the local machine is a major plus point of X and it is something which Windows desperately needs with having to hack the system with various 3rd party workarounds.

Anyway to enable this feature run YaST:

Click on System.
Then /etc/sysconfig Editor.
Select Desktop.
Select Display manager.
Select DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN.

Set this to "yes".

Restart the X server and all will be well.

Grub Error 21

Hi,

To install openSUSE 10.2 (see previous post) I installed a new hard disk in my machine and installed it on that.

Everything went well including the install but I hit a problem when I did my first reboot. I got a Grub error:

Grub Loading Stage 1.5
Grub Loading please wait....
Error 21

Aaahhh! It looked to me like openSUSE 10.2 could't handle getting the boot loader right for a multiple disk machine. But I was wrong the problem was all mine.

Before discovering the problem I used the various excellent boot modes from the install DVD and I was able to restore the old 10.1 boot loader and boot back into 10.1. From there I started looking on the web.

Error 21 means "Selected disk does not exist. This error is returned if the device part of a device- or full file name refers to a disk or BIOS device that is not present or not recognized by the BIOS in the system."

Weird, I knew the disk was present as I just installed 10.2 on it! After lots of head scratching it turned out that I forgot to add the second disk to the BIOS. The 10.2 installed didn't rely on the BIOS information to find the disks, so it was able to detect and install onto the new disk with problem. However Grub uses the BIOS information to get the disk configurations.

So once I added the disk to the BIOS it all work fine! :D

First impresions of openSUSE 10.2

I downloaded and installed the DVD version of openSUSE 10.2 and my first impressions are that it is a good, stable and feature rich release.

I prefer KDE over GNOME and this version uses 3.5.5. The star menu has been spruced up and a new multi-pane sliding thingy which looks nice but I feel that over time I might start to get quite annoyed with it, we will see.

I liked the 10.1 release and 10.2 doesn't contain any major shocks or changes.


I like it, 10/10... More once I have used it in anger!

The Linux Equivalent Project is an attempt to provide a database of Windows software and the Linux equivalent. It is still very much in beta and the page design is very simple, however it is quite a good idea.

Hi,

I'm a SUSE fan and it has been my distro of choice for several years now... So for me it is great news to hear that 10.2 has been released. I am downloading it as we speak!

It is available for download (via HTTP and torren) at http://download.openSUSE.org in x86, x86-64, and ppc versions.

The DVD edition contains more than 2,500 packages, including GNOME 2.16, KDE 3.5.5, Firefox 2.0, F-Spot 0.2.2. OpenOffice.org 2.0.4 now has a preloader that accelerates the launching of individual applications.

There is also an add-on CD with proprietary applications like Acrobat Reader, Java, RealPlayer and Opera.

More once I have finished the download!
