Bug ID: 76224
Assignee: mesa-dev@lists.freedesktop.org
Summary: client with DISPLAY set to REMOTEHOST:0 tries to load
local, unconfigured DRI drivers and fails
Severity: critical
Classification: Unclassified
OS: Linux (All)
Reporter: freedesk...@tlinx.org
Hardware: x86-64 (AMD64)
Status: NEW
Version: unspecified
Component: GLX
Product: Mesa
This is a regression from the pre-DRI and/or pre-wayland versions (i.e. -- this
used to work.
Now, when a Mesa-using program tries to open/use OpenGL, it ignores the value
of the DISPLAY and tries to load a driver on the local host. This fails as the
local system, being a [rendering, et al.] server has no local display but
expects to send it's output to a remote client.
This works for X-only programs -- and used to work OpenGL. In fact, the
infrastructure still works (good news) -- it correctly detects the remote
client's OpenGL abilities, supported features, extensions, etc... But,
having detected such, it still tries to load a local client -- swrast seems to
be the default but why it is loading when it isn't rendering locally isn't
clear (maybe it's a default?)
I note, that another remote technology XDMCP (I'm just using DISPLAY
forwarded back to the host over tcp) also stopped working around the same time.
I don't know if it is related or not, but since it involves a remote X
display, it seems possible.
This seems to have started in my opensuse's, post 12.1 release.
Current Mesa version is at 9.2.3. w/Xorg-x11 @ 7.6_1 in opensuse 13.1.
I did report it this to open suse, but they claim remote display of opengl is
not something they can support -- but it used to be a supported technology that
worked.
