Ubuntu 9.04

Have any of you guys tried Ubuntu 9.04? I just installed it in VirtualBox and I'm fairly impressed. It boots quite fast, and the desktop effects even work when installed in a virtual machine.

For my daily use which includes running VM's quite frequently, IO contention was a real pain point.

I lack the vocabulary to explain how much nicer things are with 2 FAST SSD's splitting the load from the host and guest OS.

Yes, if you have the right SSD's the difference is night and day.

FWIW, I made the mistake of buying the OCZ Core series SSD before the X25. Due to a crappy JMicron controller, the OCZ Core series would frequently stall during random writes.

The lesson... be careful when buying an SSD, performance can be radically different from brand / model to brand / model.

Quate from my own post:
"Yes I think its bad packet or so on x32 (because on x64 I can install it and works (but then axiom crashes)).. when open using x32 ubuntu's "Restricted driviers" window, there is nothing."

I remembered wrong (few weeks ago i change 2st motherboard+junk to my 1st computer's case so I didnt remember that in this (x64 box))
isnt 1950, but what dxdiag shows -> ATI Radeon X300/X550/X1050 Series, even older that 1950, but restricted drivers work on this. But not
on that second computer with 1950 card (in 8.10 these works, so ATI(amd) hadnt make good drivers yet).

Kamujin:
"(PS virtual box 2.2.2 is out and should fix the cursor problem I think)"

Works with compiz? Thats the problem i had, and when i disabled that, cursor shows again (on 2.2)

There is beta3 or 2.5 or what that was, but no windows binaries, in linux you can compile it, maybe there is
even better 3d support and faster .... one thing Im missing virtualbox, everytime when im too long using virtualbox, i forgot, that
i must mount shared directories (xp: net use x: \\vboxsvr\SHARE and in linux: sudo mount -t vboxsf SHARE S (where S is my directory)), why
virtualbox automatic mount these when choose directories to share. Well, make .bat or .sh scripts, but if forgot these (like i do),
then searching solutions from net, everytime..

@Fiddler Yep, I'm very happy with the open drivers for day-today use in 9.04. Just a shame I can't use it for OpenGL dev with this older card.

@ puklaus: I'm running Ubuntu x64. I got exactly the problem you did on installing the ATi drivers - the graphics crashed and not even ctrl+alt+F1 worked.

I don't know why I didn't think of replacing Xorg.conf... I prety much forgot all the new lessons I'd learned when I started on 8.10.

I used it as an excuse to order a new card today anyway - an nVidia GeForce GTX 260 (figured I'd switch from ATi if their Linux support is so crap).

Like Kamujin, I've found 9.04 to be a dream compared to 8.10, but part of 8.10's nightmare for me was being compeltely new to the OS. It ook me the first 2 weeks to fix my sound (had to blacklist the drivers for my second sound card), and a week and a half to set up the dual monitors (which, thanks to the improved open source 3D drivers, is much easier in 9.04).

Much as I hate to admit this, nvidia is the way to go on linux right now.

I am using an radeon 4850 which is pretty solid on both OSes, but I also develop on a laptop with a geforce 8400 (nvs 135 mobile, actually). The latter tends to behave better in opengl: it's more stable when you specify an invalid parameter (raises an opengl error instead of crashing), it tends to have less bugs in newer functionality (e.g. shadow cubemaps or framebuffer blit) and it exposes way more extensions (e.g. geometry shaders and direct state access).

On the other hand, nvidia is too forgiving with its GLSL implementation, which is a pain portability-wise. For example, there is no error when you forget to set a (required) precision qualifier in GLSL 1.30 - a bug like this is very easy to slip through, if you don't test on ati hardware (intel is not in the game, so it doesn't count).

Finally, nvidia's drivers are miles ahead on linux feature-wise (e.g. tearless video and compiz, video decode acceleration). On the other hand, ati's drivers tend to be more stable on windows, compared to nvidia's, esp. in multi-monitor setups. Ati also have the (arguable) advantage of open specs and open-source drivers on linux.

In the 1990's ATI developed a well earned reputation for shipping decent hardware with horribly bad drivers.

To this day, ATI cards are prone to conflict with each other when you try to build 4-8 monitor workstations with them. My company deploys all of it's workstations with 4-8 monitors running 1920x1200 resolution. We have found nVidia and Matrox to be the leaders in multi-monitor graphics. Our current builds use 2 of the nVidia Quadro 450 NVS to drive 8 monitors at WUXGA. My company is not doing 3D graphics on them, mostly business apps with accelerated GDI. Maybe this is why we have come to different conclusions about the stability of nVidia's and ATI's drivers in multi-monitor configurations.

From what I've gathered ATI's OpenGL implementation more correctly follows the specs, but that's not enough to get me to buy their products.
