Tried out Ubuntu’s latest version (8.10 - The Intrepid Ibex) over the weekend on a laptop and a old Dell desktop, both of them works without any problem. The big improvement for my laptop (Toshiba Tecra-S1) that I noticed is the xorg settings in gnome for external monitors. I didn’t need to go and change the xorg.conf manually this time, I only need to set it from the GUI, restart and everything works. It even works on a 22″ HD ready monitor (LG 22LS4D) displaying the correct resoluation (1920×1080) which didn’t work with Ubuntu 7.10 nor 8.04. I would recommend trying this version if xorg hasn’t been working properly for you in previous version.

Another additional feature that I found interesting is that it allow auto login, so you no longer have to type in your username and password on startup. The default timeout for this auto login is 10 seconds, which I can see is quite handy if you are using it solely at home as a desktop but obvious the draw back is that the system is less secure if auto login used. Haven’t found any problem with it yet, another great release, thanks to everyone who worked on this!

For some reason I didn’t keep up to date this time, I only found out about the new Ubuntu 7.10 Gusty release being told by a friend. I think my demand for my home PC is dropping, mainly using it for surfing the internet really! Surprisingly the new release doesn’t work for me!

So no luck for me with Ubuntu this time because firstly the upgrade manager (7.04 to 7.10) wouldn’t work… so I did a fresh install (keeping my /home directory). After that everything seems to work but it wouldn’t display correctly on the external montior (Xerox XA7), I tried almost all the settings I can think of including manually editing the xorg.conf and using the auto-config tools, just wouldn’t go above 800×600! Imagine a 19″ monitor on 800×600 resolution! I can stand a lot of the features not working, but working on a proper resolution is one of the min. requirements.

As much as I like Ubuntu, I have decided that I will try something different, may be something very simple, something very fast and stable, doesn’t have to look good but run very fast on my laptop (Toshiba Tecra-S1), and of course supporting 1280×1024. Decided to try out FreeBSD and may be with gnome 2 since the main upgrade in Ubuntu 7.10 is the support of the new gnome, but I know that it’s very possible that it’s gnome 2 which is not compatible with my monitor and or my ATI graphics card! Will see how that goes, but conclusion is, simple is good…

On a side note, about simplicity, I have come to like a very old text editor (VI) very much. It must be one of the oldest text editor that comes with Linux, it’s great because it’s so simple, don’t even need the mouse to operate it, your hand can stand on the keyboard all the time while performing search, replace, etc… There are Windows version (e.g. VIM) which people have developed. Also I’m using a web browser called Epiphany is great too, very simple and fast, but less feature as compare to FireFox. Something that’s worth trying out.

Managed to solve the problem with getting a blank screen while loading gdm after upgrading a desktop from 6.10 Edgy to 7.04 Fesity Fawn. The desktop has a ATI 9600 graphics card and works fine on 6.10 Edgy, however after the upgrade to 7.04, it starts having this problem. I knew it’s something wrong with the Xorg like many others, after trying a few changes in the xorg.conf without success, I ran the autoconfig for Xorg and that fix the problem, the command is:

sudo dpkg-reconfigure xserver-xorg

What that basically did for me to finding the HorizSync and VertRefresh, most importantly it changes the driver from “ati” to “vesa“! Initially I thought the problem was just that it doesn’t have a correct sync value, however when I changed the driver back to ati it gave me a blank screen again. So will have to use the vesa driver for a while until the problem with Xorg is fixed. Anyway, after configuring your xorg.conf or ran the command above, restart gdm by:

sudo /etc/init.d/gdm restart

everything should be running :).

The new Ubuntu 7.04 Feisty Fawn is released today! I’m very impressed by Ubuntu for having a new release every 6 months. I have been using the beta version for a while so I can’t test the upgrade function, which I had problem with before when I upgraded 6.10 to 7.04 beta but that problem should be solved with this final release. Although I can’t try it on mine, I will try it on other laptops later when I get a chance.

• Get Ubuntu / Upgrade instruction

My experience with 7.04 has been good and the new feature of supporting music sharing should quite attractive to many people. If you are interested in finding out more about my experience with Feisty or Ubuntu in general, these are some of my previous posts:

– Update 20/04/07 –

Just downloaded a CD for upgrade, ran it on a desktop (AMD) with Ubuntu 6.10 installed. Everything ran smoothly until the restart, it loads up to the point where it try to initiate Xorg but it returns a blank screen. Still not sure where the problem lays, will work it out when I have time…

Setting up additional features for Ubuntu

• Setting up 3D support and Beryl
• Google Earth
• Xubuntu - Xfce desktop instead of gnome

Unresolved issues

• Couldn’t get Direct 3D to work on external monitor at 1280×1024 resolution, therefore Beryl can only work on 1024×768.

Configuration Files

• Sources.list - /etc/apt/sources.list - follow this guide to add extra repositories
• Menu.lst - /boot/grub/menu.lst - Startup menu for choosing which OS to enter
• Xorg.conf - /etc/X11/xorg.conf - Some changes to get 1280×1024 resolution to work on 19″ Xerox XA7

Spent some time today trying to get Beryl to work on my Toshiba Tecra S1 running Ubuntu Feisty 7.04 beta with ATI Mobility 9000 graphics card. To start I used the following xorg.conf settings:

Section “Device”
Identifier “ATI 9000″
Driver “radeon”
Option “DRI” “true”
Option “RenderAccel” “true”
Option “EnablePageFlip” “true”
Option “XAANoOffscreenPixmaps”
Option “DisableGLXRootClipping” “true”
Option “AddARGBGLXVisuals” “true”
Option “AllowGLXWithComposite” “true”
Option “AGPMode” “4″
Option “AccelMethod” “XAA”
Option “ColorTiling” “on”
Option “AGPFastWrite” “on”
Option “GARTSize” “64″
BusID “PCI:1:0:0″
EndSection

Note that I used the driver radeon instead of fglrx and with xgl loaded. With these settings, I could get direct rendering on, can check yours by:

$ glxinfo | grep direct
direct rendering: Yes

After restarting Xorg, installed Beryl with the following command:

sudo aptitude install beryl beryl-manager emerald-themes

After the installation, I started the Beryl manager, however Beryl doesn’t start automatically. I ran the command beryl in the terminal it returns with the following error:

Checking maximum texture size : failed

Root window size (1280/1024) is bigger then maximum texture size (1024×1024)

From some online resources, I find out that I can use driconf to set the graphics card to have allow_large_textures = 2. However this didn’t solve the problem for me, later I found that I can set GARTSize to higher in xorg.conf. I tried:

Option “GARTSize” “256″

After restarting Xorg, I was able to run beryl without the error given before. However it returns a white screen, restarted Xorg again and find that direct rendering is off. It was found that setting the GARTSize to anything larger than 64 will set direct rendering to off. Knowing that I couldn’t get it to work on 1280×1024 on the external monitor (19″ Xerox XA7), I tried it on lower resolution 1024×768 and got that to work with the following screenshot:

Given that you are not using an external monitor, it would work on the laptop monitor on resolution 1024×768. The function shown in the screenshot is really the only function that I want from Beryl, and knowing that ATI doesn’t work very well with Beryl/Compiz anyway, don’t think there is much I can do to make it work on 1280×1024 unless new drivers come on or with another graphics card.
