Slow GUI
Hi, My problem is so basic that I even fail to figure out what to debug/benchmark/google, etc. My computer feels amazingly sluggish in everything that is UI-related. For instance, it takes some 10 seconds for Firefox to fire up (counting from the click on the icon). Same with Konsole -- 5 seconds. Firefox window maximization -- 3 seconds until the actual window maximizes, and some more seconds until all the menus/panels are redrawn. The time from clicking on a checkbox in a webpage till the V sign appears is also noticeable. It happens with both Qt and GTK applications. The machine is more than strong enough for GUI tasks -- it's T7300 with 3Gb RAM with i965 graphics. The CPU level is around single percents. The software is Gentoo Linux, KDE 4.2.3. Fedora 10 on the other box I have feels MUCH more responsive. The only difference I can think of is that it has nVidia graphics card. hdparm shows 50 MB/sec (a bit lowish, but doesn't explain orders-of-magnitude slowness I exprience). md5sum of zero-filled file of 1 Gb takes 8 seconds (the second time, so that it will be read from the cache). I can't think of other tests. ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

Regarding engraving on the keyboard hebrew, I know there is someone in tel aviv which does it for around 100 nis. I didn't do it, but if you want I know someone who did and I can ask the phone number. As for the warranty, sony indeed are nasty in this field.

Re: upgrading ubuntu to debian
geoffrey mendelson wrote: I am currently running Ubuntu 9.04. I am fed up with it. I want to replace it with debian, hopefully without wiping the hard drive in the process. I looked around and found an Israeli mirror but there are something like 31 cd's or 5 dvd's and updates. Is there a simple way to upgrade it it, like changing the sources file for apt and doing a dist-upgrade? If not what do I download and what do I do with it? Note that I have 2 systems to upgrade and is there a way to not have to download everything twice? I have a fast enough Internet connection that I could download the DVD images one per night while I am sleeping and burn them to DVD's during the day if need be. If I use jigdo instead of a straight download do I get custom dvd's up to date, or the same ones as if I dowloaded the release images? Thanks in advance for any advice. Geoff. Ok, let's try to answer all questions. First - you do not need to download everything. You can perform a complete Debian install with no more than the first CD. You would still need to download certain stuff from the internet, but this is a small amount in comparison. Most everything you need is on the first CD. If you already have an APT system set up, you can use a tool called apt-proxy. If you put that as your apt source, it will cache the packages you download. This way, you can perform a full network install, and yet not download anything twice. This is the most compact (download wise) setup you can do. With only two systems, I'm not sure it is the most efficient, however (especially since one of those system will need to be the proxy, obviously). Turning an Ubuntu 9.04 system into a Debian system (you didn't say whether it is Unstable, Testing or Stable) is, likely, not possible using only apt operations. One thing you can do is use debootstrap to setup your debian system in a new partition, and then switch over to it. Not for the novice, but the most difficult parts are getting the kernel and boot loader into system, so not brain surgery either. If you decide to go the CD/DVD route, it doesn't matter how you download. Jigdo will not give you more up to date image than the latest ISO. You can use jigdo in combination with apt-proxy, so it is not totally useless (I always use jigdo for downloads, mostly because it allows upgrading an older image, or from the i386 to the amd64 image, without re-downloading everything from scratch). The easiest is if you have a separate home partition. Just reinstall the base system, leaving the home partition alone. There will be some tailoring to do (versions don't match exactly, you will not remember to install all packages from the get go, etc.). When I do such transitions, I always save the old etc directory somewhere, so I can pick up things I forgot later on.

Unlike the Israeli warranty, which was same day, they only promised five work days, but still I did not have to pay for the fix. Same goes several months later when the battery and CD malfunctioned (the battery was dead, and the CD would not burn). The batter was replaced a week before its warranty expired. It is also worth mentioning that the keyboard was fixed by replacing it with a new one. Needless to say, the new keyboard was a Hebrew/qwerty keyboard, so that was another problem solved.

Re: Changing Xserver driver from vesa to openchrome gives ICE I/O error
Hello Oleg, I was on vacation the last week and could not thank you for a response. I made configuration the way you describe and it works. So thank you again.

I tried to use vga boot parameter so vga=792 but I got I a blank screen 2. now I am thinking to use Modes that Xserver prints in Xorg.log file, and I wonder if these modes anyhow corresponds to vga boot modes? 3. Why Xserver itself ( I am not using window manager) is not capable to fulfill geometry requests, i.e running xterm -g +0,-0 from .xinitc does not place it in a bottom ?

You can run # Xorg -configure to generate a skeleton xorg.conf file (IIRC, as /root/xorg.conf.new) and edit it to your heart's content.

Re: upgrading ubuntu to debian
Hi, I wouldn't start with upgrading from Ubuntu to Debian, it will get messy. Just upgrading from Debian stable to testing is a big headache and usually will break the system. It is much easier and quicker to net install a new Debian. As to upgrading two systems, just install the first, and then tar.gz the Debian root file system and copy it to the second. I don't know how to preserve the packages you already installed in Ubuntu. So it takes a week or too, to find what is missing and install it on the new system. Its not smart to just install all the packages you had in Ubuntu, because it will get a lot of unused packages (but it can be done). Net Install: This is the best way to install the system, because it downloads just the packages you need. I usually install the base system. Finish the installation, restart the computer and use aptitude or dselect to install the rest of the system. Grab the mini.iso and burn it from here: ftp://ftp.de.debian.org/debian/dists/unstable/main/installer-i386/current/images/netboot/ This will start your net install.

Hi all! The Tel Aviv Open Source Club invites everyone to a talk by Yaron Meiry (Sawyer) about Programming Red Flags - on Sunday, 21-June-2009 The meeting will take place at Tel Aviv University, at the Schreiber MathsCS building, room 008 on 18:30. So mark your calendars. More information can be found at: * http://www.cs.tau.ac.il/telux/ * http://wiki.osdc.org.il/index.php/Tel_Aviv_Meeting_on_21_June_2009 Attendance is free and everyone are welcome. With any other problems, feel free to contact me: http://www.shlomifish.org/me/contact-me/ Abstract: - Some programming habits should be avoided at all costs; some should be considered with care and some are just divine. Red flags tell us what to try and avoid and what to inspect more closely. They are a sign of code that might become problematic or straightforwardly dangerous. The talk will be Perl- oriented (with Perl examples) but the programming practices are generic and can be applied to most programming languages, so if you program in Ruby, Python, PHP or other languages, this talks to you as well. Hopefully by the time we're done, you'll be able to write cleaner, more maintainable, less error-prone, and better code. If not, your money back guarantee! -- We are always looking for presentations on interesting topics. If you have an interesting idea for a talk, feel free to contact us and we'll co-ordinate a date.
