        In a few days I will have a Pi4 (4GB). At the moment I can run Marius' image on my Pi3 although the scaling is out (on a HDMI montor and on the 7" Pi touch screen) and it tends to freeze when the browser is run. I got a wee bit stuck until I realised "phablet" was the passcode it asked for 🙂

          @Aury88 :
          If you used your 64GB SDcard, try a 32GB one or, after using dd, use gparted to create a 33GB partition at the end of the SDcard. This could help to break the reboot loop.

            What was necessary to launch the graphical interface starting from console mode, please ?

              in the 64GB SDcard, after using dd and adding a 33GB partition at the end of the SD Card I have the following kernel panic:

                Woooo 😞
                Sorry, no more idea to try to help you.
                When I'll be home, I'll give you the sha256sum of my image file to be sure that we have the same

                  I sacrificed my smartphone 8GB sdcards and whit the UT image it "work". I was able to login and explore the system in console mode. but was not able to see the DE (it says unity8 is running and after restart unity8 nothing change)

                    Just back home ... Fine that you were able to explore the system in console mode.
                    This confirm that 64GB cause problems not only in the case listed in the link above ...
                    I'll take some time to try graphical mode. I'll report here.

                    People who know how to launch the graphical mode are welcome to explain here !

                      Sorry but I didn't understand how to launch the graphical user interface.
                      And with a console mode only, I don't see what to do with it ...
                      I hope someone will describe the solution.

                        Hello,

                        Nobody (knows how) is interested in running Ubports in graphical mode on a Raspberry Pi4 ?

                        Have a nice day

                          Well I, for one, am following UT on Pi with great interest, @Pulsar33.

                          I'm still at the "Kernel Panic" stage though, so I can't help much. Sorry.

                            Hello,

                            Thanks for your answer, @3arn0wl

                            To be sure that we all use the same image, here are the sha256sums of the #8 latest stable build (2019 09 25) I use :
                            ubuntu-touch-raspberrypi.img.gz febf1ce00e639ae469bf075bce4472b82b25a6d634a147c01d666f1d4f5033c0

                            The flashing process on my Linux Mint 19.2 Desktop :

                            lsblk   # the SDcard appears as /dev/sdc
                            umount /dev/sdc1
                            umount /dev/sdc2
                            sudo dd bs=4M if=ubuntu-touch-raspberrypi.img of=/dev/sdc status=progress

                                The unity8 log is very similar to this issue in mir-kiosk. It says there is a workaround but I don't understand what it is....we need to study it and or help from @alan_g

                                it seems we need to

                                --env-hacks MIR_MESA_KMS_DISABLE_MODESET_PROBE
                                

                                when run mir/unity8 but I don't undestand how...

                                  also we are using an old rootfs with missing firmwares (last building image is the #8 from 24 September when the firmwares integration in the common rootfs is from 3 October )

                                    That's just one way to set an environment variable.

                                      @alan_g sorry but I'm not so skilled about bash and linux. so excuse me for the stupid question:
                                      I knew that environment variable had to have a value so something like

                                      ENV_NAME=value
                                      

                                      MIR_MESA_KMS_DISABLE_MODESET_PROBE seem only the name...what is its value? is it"true"?

                                        @alan_g sorry but I'm not so skilled about bash and linux. so excuse me for the stupid question:
                                        I knew that environment variable had to have a value so something like

                                        ENV_NAME=value
                                        

                                        MIR_MESA_KMS_DISABLE_MODESET_PROBE seem only the name...what is its value? is it"true"?

                                        It doesn't need a value, so "true" will be fine (as will "false").

                                          no, setting that as an enviroment variable didn't solved the problem... ¯\(ツ)/¯

                                            Hello
                                            Still stuck in console mode.
                                            Please tell me the commands to try launching the graphical mode, even if this doesn't succeed at this time.

                                              @Pulsar33 it should be in the Ctrl+Alt+F7. unity8 is by default already running in background. you can prove that by typing in the console

                                              start unity8
                                              

                                              Also you can restart it with

                                              restart unity8
                                              

                                              The problem is that it doesn't seem to work properly because of the mesa-kms missing support in the raspberrypi4 as you can see above
                                              (EGL platform does not support EGL_KHR_platform_gbm extension, Failed to detect whether device /dev/dri/card1 and card2 supports KMS and Couldn't get DRM resources for an Invalid argument)
