| miculou | hi all, how do you run apps on mir from the CLI? | 11:52 |
|---|---|---|
| miculou | on unity8/desktop | 11:53 |
| anpok | depending on the toolkit you have to set specific flags.. since they might find a DISPLAY env var.. so GDK_BACKEND=mir QT_QPA_PLATFORM=ubuntumirclient SDL_VIDEODRIVER=mir MIR_SOCKET=/run/user/YOU_USER_ID/mir_socket | 11:55 |
| anpok | unset DISAPLAY.. | 11:55 |
| anpok | then depending on the applictation unsetting QT_QPA_PLATFORMTHEME is also necessary | 11:56 |
| anpok | oh and for unity8 to accept the connection of a starting application it needs to find a desktop file | 11:57 |
| miculou | anpok: i'm trying to run supertux2 (sdl2 i think) | 11:58 |
| ogra_ | just look up ubuntu-app-launch ;) | 11:58 |
| anpok | it gets either via ubuntu-app-launch or by looking at the command like parameter | 11:58 |
| miculou | i tried both ubuntu-app-launch and -- --dektop_file_hint etc | 11:59 |
| miculou | with ubuntu-app-launch i can see a windows + the loading spinner but then it closes | 12:00 |
| miculou | and with -- it complains that the args are wrong wich they are | 12:00 |
| miculou | i'm not even sure if the sdl2 in ubuntu has mir enabled, that's an option on compile.. i think? don't know very noob lol | 12:04 |
| ogra_ | it does | 12:04 |

| miculou | i don't even know what i'm doing! :)) | 12:06 |
| anpok | you try to connect to a system compositor | 12:16 |
| anpok | the system compositor only allows full screen clients (aka greeters/session shells) | 12:16 |
| anpok | so try the mir_socket of the unity8 session instead.. | 12:16 |
| anpok | (/run/mir_socket is opened by unity-system-compositor) | 12:16 |
| miculou | oh, i see, so this bit MIR_SOCKET=/run/user/YOU_USER_ID/mir_socket | 12:18 |
| miculou | ? | 12:18 |
| miculou | let's see | 12:18 |
| anpok | yes .. should be 1000 in most desktop installations | 12:18 |
| anpok | and if you launch it from a unity8 terminal .. you would not have to care about that part.. | 12:19 |

| anpok | attente: hm not yet.. | 16:44 |
| anpok | i mean we could add an example server that does that.. or a client that reconfigures the desired content scaling | 16:46 |
| attente | anpok: how did you test your MirSurfaceOutputEvent patch? did you use a hi-dpi monitor? | 16:50 |
| anpok | attente: printf... only.. | 16:53 |
| attente | anpok: but is there some way to trigger a MirSurfaceOutputEvent? | 16:54 |
| anpok | on recent mir servers you should get one after creating the surface | 16:59 |
| anpok | and then when you move the surface over to a different output | 16:59 |
| anpok | hmm I am afk for 2.5 hours.. I think I can come up with some test client to play with the scale value | 17:00 |
