I can't believe it, but I guess this is actually my first post within a week of the last one. Well, I decide to post some ideas, since I'm waiting for some results of my simulations.This are my weekly News1- I have updated the video drivers (to Catalist 9.2) (see previous post) !!! I un-installed the old ones (9.1) from the console and installed the new ones from the console (no restart in between). When I restart everything seemed to work perfectly... yes, only seemed. I have to admit that I'm very happy that I have no need to re-install the touch-screen support in my laptop after updating the video drivers (yeah, I know it sound weird, but in this laptop the ATI motherboard relationship seems to be extremely intimated).2- I haven't have time to check the audio output behavior so far, I will this weekend.3- I gave up on Evolution. Move all my files back to Thunderbird, with some minor problems, but now everything is ready to get rid of Evolution. Sad. But I had no freezing situations using enigmail.4- The Network Manager/Management seems it the same situation than last week... sometimes I connect, some times I don't. Still don't know why.5- I still have the same problem with sessions...6- I haven't tried Hibernation yet.7- I haven't work on the screen rotation8- I'm working now with Eclipse, subclise (the subversion plug-in), SFTP (to send my latest code to the cluster where my applications run) and yesterday I installed the valgrind plug-in. I'm really exited !!!9-On the negative side, I got 2 freezing situations: 2009-03-12 - 15:50 and 2009-03-12 - 17:03. I guess if could be because of the video drivers.... I'm going to try to be more consistent in this.This weekend plans are:A) to test of the functionality and evaluate the new updated software packages. I just installed Banshee 1.4.3B) to have my camera ready to document weird video output. Could Banshee be a replacement of Rhytmbox+Miro ?

I'm BACK !!!
Several Months without posting... well, I'd been busy with my work, I traveled to South America, and I got a new laptop. I have (since the beginning of the year) a HP Pavilion tx2500. It's a nice machine, good weight and size, with touchscreen.
I'm running Ubuntu 8:10 on this laptop. I works OK most of the time, however I have some problems I can't fix yet:
1 - Audio
The laptop has 2 outputs for sound (left and right). I plug my (only) one (male) plug into one of them to have sound in (external) speakers and not in the speakers of the laptop, same thing with my headphones (to avoid bother other people in the room). However, almost every time I reboot I have to switch the plug to the other output to obtain the same results (no output in the internal speakers and output in my headphones/external speakers). I don't know if it is Ubuntu or the kernel or alsa or pulseaudio.
2 - Evolution.
I love the integration of evolution with the desktop, however sometimes when I use PGP evolution crashes the whole system (not ony the e-mail client). I wrote to the evolution development team, and I have no answer. Thus, in a few days I'm going to start my migration to Thunderbird. It's really sad.
3 - The Network Manager/Management.
This is also another "randomly on-off" situations. I'm connected to my home (I should say "the house where I live") wireless (which I don't administrate). Sometimes, I just can't connect, so I need to reboot (yes, reboot) until the network manager allows me to connect. I tried restarting the network from console, I tried running dhclient from the console, no results. I need to restart, and the "voila" the network is running.
4 - Sessions.
I'm clearly a bit stupid because I don't understand how to work with sessions. I tried to save my (current) session, so the next time I start my computer I have OpenOffice open in the document I'm working, firefox in the newspaper I read, etc, etc. I tried, System->Preferences->Sessions and in the Options tab i checkthe box ( Automatically remember ...). Then I reboot, and .... nothing ! The same old desktop, no application (re)started. So, I tried the other way, I installed ubuntu tweak 0.4.6 and tried the same thing (Session Control).... with the same result !!!
5 - Hibernation.
Mainly because of the failure to remember the applications in the state that they were before logging out, I tried to use hibernation. A total disaster, although I must confess that I was running some simulations very CPU demanding when I tried to use it. I'm going to try later today or this week and see....
6 - Video drivers/Rotation.
I choose (erroneously) to have ATI video... I thought well, ATI and AMD are now friends and AMD allways was very friendly with the open source community and Linux, so ATI is going to have a increadible good open source drivers and try to compite with NVIDIA in the "user friendly" front (because clearly can't compite in quality, speed, performance, etc.). WRONG ! I'm still using binary (close) drivers, that are bad for reproducing video (the area were the video is reproducing keep refreshing, then the reproduction is a set of flashed images). One of my friends told me that it is because Compiz and the video driver are not talking correctly to each other.... I'm able to reproduce video correctly if I use VLC and set the output to X11. Supposedly because of the same reason, the scripts for rotation of the screen using xrandr . I'll try this week with the new ATi drivers (9.2)
7 - Eclipse.
I have to install manually Ecplise Gamynede (version 3.4.x), because Ubuntu repositories have
the previous to the previous version (3.2.x). Yes, really really old repositories, which made me think about it, If no one is going to update that packages.... do we really need that there ?
Any ways, I will keep trying to inform people on what is going on. I stalled Drivel and hopefully it will be easy to blog with it :)
In the meantime at least I learn one lesson: Buy NVIDIA, ATI is lower quality and as bad as NVIDIA regarding the open source community.
One more thing: Don't get me wrong. I'm really glad and thankful to the ubuntu community, but I guess that this are things that still make Ubuntu (and linux) hard to access to the regular user.
