Public bug reported: Xmir crashes immediately on startup using glamor on Nexus4.
glamor GL version: OpenGL ES 3.0 [email protected] AU@ (CL@) ... glamor GLSL version: OpenGL ES GLSL ES 3.00 (EE) (EE) Backtrace: (EE) (EE) Segmentation fault at address 0x0 (EE) Fatal server error: (EE) Caught signal 11 (Segmentation fault). Server aborting (EE) The stack trace is lost. However the problem appears to be the glGetStringi() function. This function is new in GLESv3 and libepoxy only uses it because the GLES version is 3.0 on mako. However, libhybris fails to implement glGetStringi() and forward it to the driver correctly. At least that seems to be the problem. Our hybris GLESv2 is missing the function but the Android GLESv2 on the device has it. ** Affects: libhybris (Ubuntu) Importance: Undecided Assignee: Daniel van Vugt (vanvugt) Status: New ** Affects: xorg-server (Ubuntu) Importance: High Assignee: Daniel van Vugt (vanvugt) Status: New ** Also affects: libhybris (Ubuntu) Importance: Undecided Status: New ** Description changed: Xmir crashes immediately on startup using glamor on Nexus4. + glamor GL version: OpenGL ES 3.0 [email protected] AU@ (CL@) + ... glamor GLSL version: OpenGL ES GLSL ES 3.00 - (EE) + (EE) (EE) Backtrace: - (EE) + (EE) (EE) Segmentation fault at address 0x0 - (EE) + (EE) Fatal server error: (EE) Caught signal 11 (Segmentation fault).
