Public bug reported:
$ sudo bin/mir_demo_server_basic --launch-client
bin/mir_demo_client_eglplasma
[Exit server using e.g. Ctrl+Alt+Backspace]
$ sudo bin/mir_demo_server_basic
ERROR:
/home/alan/display_server/mir4/src/platform/graphics/mesa/display_helpers.cpp(234):
Throw in function int
mir::graphics::mesa::helpers::DRMHelper::open_drm_device(const
std::shared_ptr<mir::udev::Context>&)
Dynamic exception type:
boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::runtime_error>
>
std::exception::what: Error opening DRM device
-22, "Unknown error -22"
The problem doesn't arise if starting the client separately. So I guess
using "system()" to start it allows too much to leak between processes.
NB this issue also blocks switching back to X
