Frustrations: Dual screen Linux

Posted by linuxhappy on March 27, 2008

Okay, this post is more or less going to be rant about the past 4 hours. I had Fedora Core 8 on my box.. A dell GX620.. it’s got an Intel 82945G/GZ Integrated graphics chip. FC8 has been ‘ok’, I really didn’t get too much mileage out it because was sshed into it most of the time, and also I wasn’t very attracted to the fact that I had to download about 800mb of updates right after installing it.. The other turn off was the fact that compiz worked once.. and then I rebooted my machine, and then Fedora told me that it could no longer run compiz. UGH!  Anyways.. at around 2pm today, I have a need for a Linux dual screen system. Since I’ve heard so many great things about Fedora Core 8, I figure I give dual screens a whirl. Well.. I tried a couple of the screens and graphics resolution gui’s but all I got were cloned desktops… no help. So seeing how I wasn’t impressed with Fedora Core 8 anyways, I figure I dump it like a smelly x girlfriend and move on to ubuntu 7.10.

A long story short, Ubuntu 7.10 didn’t seem to solve my problem either. The first time I booted xrandr noticed I had a VGA out and a DVI out, but upon following some instructions here:

xrandr seemed to only want to notice only one (vga) of my video ports. Somehow after running `sudo dpkg-reconfigure -phigh xserver-xorg` everything when crazy. Soo after about an hour and a half of trying to get back to where xrandr was seeing two screens, I gave it the middle finger and moved on.

Ubuntu 8.04 is still in beta, and I really hate beta software, but I figure I had nothing to loose since I just formatted my machine to ubuntu 7.10. Anyways.. I was able to get dual screens within 15 minutes of booting the machine a fully installed ubuntu 8.04 machine. All i had to do was modify /etc/X11/xorg.conf with the “virtual” line and then user xrandr to move my screens around.. Some examples can be found here:

Needless to say… Linux distros needs better support for dual screens.. and making it work with compiz. I’d like some sort of gui, comparable to what microsoft windows offers.. I was hoping that the new version of gnome on ubuntu 8.04 would offer it, but the closest thing that I could find was grandr, (which is also offered on ubuntu 7.10) the frontend to xrandr.. Ohwell. Maybe one day.

Opinion: Why CVS sucks

Posted by linuxhappy on March 2, 2008

I’ve been using Subversion for about a year and a half, a I’ve been thinking about switching to git.  Well, I did the exact opposite and took 10 steps back and checked out CVS.  Why you ask? Don’t ask. (git I haven’t forgotten about you.. I’ve taken you for a test drive, but haven’t used you on anything production)  Anyways, some of the short comings of CVS that I immediately experienced were the following:

1.  No softlink support
Check a softlink into svn.  No prob. Check a softlink into cvs, you’ll never see it again. There isn’t even an option to jam the file in there.  Softlinks are files too!!!!

2.   Empty directories
Have an empty directory?  It won’t get checked in.  Ugh… Oh hey, guess what?  Lets say you have a directory with ONLY a bunch of softlinks.  You think the directory will get in there?  The answer is, well, yes.  When checking out your project, the folder will be checked out without any of the softlinks.  But what happens when you export your project?  The folder will be magically pruned away. 😥  This can create havoc on many buildsystems that expect empty directories to be there.

3.  Binary files have “issues” unless handled with extreme care.

Ugh, Yes, that’s all I’ve got.  I won’t even talk about merging, and the fact that “bad things” happen if commits to completely finish.

Software of today’s world requires software tools for today’s world.
