GDI Generic Vendor dirver with no opengl support

[hrach]

I'm opening this issue as an upstream issue for zacps/alacritty#21.
Currently, I'm unable to run Alacaritty on environment with Dell dock, since the graphics environment seems to behave and been detected as GDI Generic Vendor. After undocking and running Alacritty directly on the laptop, everything is ok.

Since the generic GDI venedor, glutin is unable to properly load and ends with error:

Error creating GL context: couldn't find any pixel format that matches the criterias.

Here I provide an output from opengl extensions viewer during docked state:

OpenGL driver version check (Current: 0, Latest known: ):
Latest version of display drivers found
According the database, you are running the latest display drivers for your video card.
No multitexturing support
This may cause performance loss in some applications.
No secondary color support
Some applications may not render polygon highlights correctly.
No S3TC compression support
This may cause performance loss in some applications.
No texture edge clamp support
This feature adds clamping control to edge texel filtering. Some programs may not render textures correctly (black line on borders.)
No vertex program support
This feature enables vertex programming (equivalent to DX8 Vertex Shader.) Some current or future OpenGL programs may require this feature.
No fragment program support
This feature enables per pixel programming (equivalent to DX9 Pixel Shader.) Some current or future OpenGL programs may require this feature.
No OpenGL Shading Language support
This may break compatibility for applications using per pixel shading.
No Frame buffer object support
This may break compatibility for applications using render to texture functions.
Few texture units found
This may slow down some applications using fragment programs or extensive texture mapping.
Extension verification:
GL_EXT_color_subtable was not found, but has the entry point glColorSubTableEXT

Is it possible to do something with this? I'm not a Rust/Alacritty developer/OpenGl developer, so I'm not much sure this whole make sense to ask.

[francesca64]

I looked at your original issue report.

Do you have this problem with other (as in, non-Rust) OpenGL applications? If so, there's likely nothing we can do.

[hrach]

I've never encountered such issue (that some app would fail/not work because of the docking), though not sure how much apps actually needed OpenGL. Are there some specific apps I could try?

[francesca64]

A lot of applications don't require OpenGL, so it's hard to think of anything outside of games. Maybe try the glfw examples? https://github.com/glfw/glfw/tree/master/examples

Fixed in #1435.
