Blank screen after upgrade to Ubuntu 7.04 Feisty

April 22, 2007 10:38 am

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 :).

Ubuntu 7.04 Feisty Fawn Released

April 19, 2007 7:31 pm

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.

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:

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…

Ubuntu 7.04 Feisty on Toshiba Tecra S1

March 30, 2007 6:22 pm

The Ubuntu 7.04 Feisty Fawn beta came out a few days ago, after finding out about it I have decided to try it out. It’s quite risky has it’s still beta version, but want to try it out and help testing it. The first version of Ubuntu that I tried out was 6.04 Dapper, then I upgraded it to 6.10 Edgy and now to Feisty, will post again after the upgrade if it still works :D.

It’s getting quite late now, the upgrade seems to run fine until I restart the computer. It has problem booting into Linux giving me an kernel panic error, seems I’m not the only having the problem! At the moment, using Ubuntu 6.10 live CD to see if I can fix it, backing everything up. In the worse case, will wait until the final version come out and install the new one instead :(.

Finally got Ubuntu 7.04 beta working, at the end I had to format my comp and do a new installation. As I had to format some of the partitions anyway I thought about installing DesktopBSD and PC-BSD but couldn’t get either of them working. The new 7.04 is good with some new features, still testing it out and a lot of updates and installations to do. In a way it’s that the upgrade didn’t work so I had to clean up my computer! Let’s see how it goes…

Fixed the problem with high cpu (100%) usage and slower response with ubuntu 7.04 compare to 6.10. Installed the xorg 7.2 and the problem seems to be solved, everything is running smoothly and as fast as before :) . To do this:

Add the following to your sources.list (i.e. sudo gedit /etc/apt/sources.list)

deb http://users.tkk.fi/~tjaalton/xorg72 feisty xorg-test

Update your apt database

sudo apt-get update

Run the upgrade

sudo apt-get upgrade

If you have EXA enable, you might want to change it to XAA first. Other than that, restart session by Ctrl+Alt+Backspace and everything should be a lot faster!

Ubuntu 7.04 detect k800i without the need of installing extra drivers. Today I just wanted to get some photos from the k800i, since I just got the new ubuntu I thought I would just plug it in and see if it can be detected. Surprisingly, it works, it detected the phone and allow me to transfer files. Thanks to the development team for such a great OS!
