I have a new dell inspiron 15n, shipped with ubuntu 9.04
Blender does not display properly… windows (when moved), menus (when opened and then closed) , at least some tools, leave blurry prints of themselves stuck on the screen, resulting in an unusable mess. Other software I have tried seems ok. Synaptic Package manager got 2.48a+dfsq-1ubuntu3 . Removing Blender completely and installingit again did not help. Please, does anybody have a fix, an explanation, a name for this problem:eek:
Probably it is the graphics drivers.
Post up more info about the graphics chipset and other hardware, maybe someone knows…
I have had similar luck with Linux and Ubuntu. It really is an OS for the technically minded. I get stuck at the simplest things, like video drivers and what not. My advice to the Linux community is to make the installers work like windows. And by that, I mean the 3rd party vendors should provide installers that you can simply click on and everything works.
Ubuntu is fairly famous for running you (meaning me) in circles. I get message like found your new hard ware should I install the drivers (WTF is it asking me anyway, just do it?). Yes, please install my drivers. Then after a reboot I get the same old song and dance. The same message is displayed and I am stuck in an infinite loop. I have a very good solution to all that, it is called format disk.
What graphics card? what driver? is it using a proprietry or free driver?
(I’ce had many dells running ubuntu over time, most had nvidia cards and the “non free” driver from nvidia: no issues!)
then again, I always build from source these days as I want/need the latest features for my work… luckilythis is usually quite easy on ubuntu… there are many guides about.
and the linux community can do what exactly to make the 3rd party vendors do that?
Some vendors provide excellent linux support,others not so much
(and ubuntu has never run me in circles like that… mileage may vary!)
Without knowing anything about your graphics chipset, I would suggest disabling the desktop effects (aka compiz).
@Atom: the question was fairly specific, not a general one about Linux. Lets not have one of those again. There are plenty of users here of all different OSes. Don’t like Linux? Don’t use it.
The laptop is supposed to have Intel Graphics Media Accelerator X4500HD… the inspiron 15n comes with ubuntu installed and is supposed to come with appropriate drivers for the hardware that dell puts in the machine. Note that the blurry doubles don’t necessarily happen when one is doing something fancy… the windows, menus, cursor are screwed
Ubuntu 9.04 (Jaunty) is notorious for having problems with integrated on board graphics chipsets (especially intel because they don’t fully support OpenGL … or DirectX for that matter, no full support for advanced shaders) . Just go ahead and upgrade to 9.10 (Karmic) and the problems will go away . Just turning off the eye candy will not resolve the issue .
Even then, the 2.4X series of Blender will not perform very well compared to 2.5 builds (it will be less responsive in the 3D view with modestly complex scenes) … But 2.5 really isn’t production ready …
If you are interested in using Linux and 3D always choose Nvidia cards when ever possible, they always have the best support even though you have to use non open source drivers …
I have the same problem on my laptop (with an Intel GMA, too), and so far I found no solution. The reason of this error is that Intel changed the structure of the chipset family (or something similar, I don’t know exactly) and their opensource driver has not yet been adopted to this change (AFAIK). Maybe their latest driver might help, but I had no luck building it. (http://intellinuxgraphics.org/)
(I must admit I haven’t tried karmic on this laptop so far)
I had the very same problem, but it was my desktop intel onboard graphics.
Since ubuntu 9.10 the problem is fixed.
I sugest you upgrade to 9.10. It should be painless and will solve your problems.
