10245	OpenGL Warning: Cleared gl error 0x500 on context creation	TechGuy987		"Hello all,

I am trying to run a Ubuntu 11.10 guest on a Ubuntu 10.04 host, and the guest freezes up when I try to log in using the ""Ubuntu"" (ie. Unity 3D) interface. If I log in using the ""Ubuntu 2D"" (ie. Unity 2D) interface, everything is fine.

I have attached the log file. From what I have read in a forum post ([https://forums.virtualbox.org/viewtopic.php?f=3&t=46120/ https://forums.virtualbox.org/viewtopic.php?f=3&t=46120]), the relevant lines are:


{{{
00:01:26.008 OpenGL Warning: Cleared gl error 0x500 on context creation
00:01:32.771 OpenGL Warning: Trying to switch contexts when the attribute stacks weren't empty.  Currently, this is not supported.
00:01:36.326 OpenGL Warning: Trying to switch contexts when the attribute stacks weren't empty.  Currently, this is not supported.
}}}

According to the post linked above, this error is indicative of driver issues. My chipset is the ATI Technologies Inc RS880 (Radeon HD 4200), and the driver I am using is the open source radeon driver (version 1:6.13.0-1ubuntu5 of the xserver-xorg-video-radeon package).

I created a forum post for my problem ([https://forums.virtualbox.org/viewtopic.php?f=7&t=47899/ see here]), and was advised to post a bug report.

Thanks in advance."	defect	closed	3D support	VirtualBox 4.1.8	obsolete	OpenGL		other	other
