I have install many applications and cheese was one of those but I can not open
I have tried cheese on debian 6.04 and cheese works fine but not on Ubuntu.
Maybe, I do not any drivers installed on the system? Because they are available. Do I have to install them?
If this is the cause of that, what can I do ,or when a driver it will be available? (I send a report 2 launchpad of the system)
and because of that I can not use neither Ubuntu 3d or gnome shell or play 3d games.
my hardware display on terminal using command lspci was:
01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] 771/671 PCIE VGA Display Adapter (rev 10)
(..just about every hardware is from Silicon Integrated Systems [SiS] on my laptop)
using cheese on terminal give me this error:
Xlib: extension "GLX" missing on display ":0.0". (cheese:4163):
Clutter-CRITICAL **: Unable to initialize Clutter:
The OpenGL version could not be determined
but after a new installation of ubuntu and update (did here a reboot)and new instalations of applications give me a different error before reboot on terminal that was:
(cheese:506): Clutter-CRITICAL **: Unable to initialize Clutter:
Unable to find suitable fbconfig for the GLX context:
Unable to find fbconfig with rgba visual
but them after rebooting after installing aplication give the same error
Xlib: extension "GLX" missing on display ":0.0". (cheese:4163):
Clutter-CRITICAL **: Unable to initialize Clutter:
The OpenGL version could not be determined
i have also installed ubuntu 12.04 and cheese works fine like for example stellarium even without a driver installed
so should i try to upgrade ubuntu 11.04 to ubuntu 12.04 beta? or wait for ubuntu 12.04 ?
i have upgrade ubuntu from 11.10 2 ubuntu 12.04 beta but still didn't work..
so i try to install ubuntu 12.04 beta from the start make a update and them install cheese it works like it did but them i also use synaptic and install all packages or applications from the markings on my ubuntu 11.10 .. and it seen all is working on the graphics better not fast but working like for exemple supertuxkart or stellarium
Looks like OpenGL extensions are not installed or functional and that also explains your issue with 3D software. First lets see what kind of graphics card do you have. Type the following command in terminal:
Look for the line with VGA in it and add that information to your question. My guess is that you have an NVidia card and you have not installed the proprietary drivers. Find the Additional Drivers utility and see if any driver is available to install. If yes, installing that should solve your issue.
Edit: Now that I see you have a Silicon Integrated Graphics card, it is clear what the issue is. I think you got somewhat lucky. I just did a quick search on the net and by looking at a blog post and this forum post on the issue, it looks like 3D acceleration was not supported for this chip at all. But from what you describe, it looks like the opensource driver available in 12.04 has got the support. So at this point you have two choices. The obvious choice which you already mentioned is to upgrade to 12.04 which isnt a bad thing specially if it is a personal laptop, and if you are learning. The other choice is to find the driver thats available for 12.04 and install that on your 11.10 if you really want to stick with the more tested version. Honestly, I think your best bet is to dive into 12.04 and enjoy living on the cutting edge for a couple of months :).
I think the answer above is incorrect. I also can not start cheese on my 12.04 setup with an NVIDIA GT240 graphics card. I am using the proprietary driver and the webcam works perfectly with Skype. Camorama does not work either.
I am using 12.04 updated today 18th April. This is Beta 2 updated.
I did a fresh installation on another machine (using the daily build) and the problem does not occur. I would suggest doing a fresh installation at the end of the month.
You need to install bumblebee and run with optirun cheese.!
