Just to clarify (i know it is a bit confusing): At the moment, almost all N900 images are broken OOTB for various reasons (updates issues, wrong meta packages, swap issues). However it is just affecting fresh installations. So at the moment, for you guys who wants to try leste without issues, i recommand you to burn last available daedalus image and modify fstab before the first boot (i.e from PC or from sdcard mounted in Fremantle): In /etc/fstab: #comment emmc swap: #/dev/mmcblk1p3 none swap sw #and add sdcard swap: /swap none swap sw That's it. The first boot is very slow as usual, so don't click anywhere for at least 3 min until the welcome message appears. You need to extand rootfs and reboot After second boot, it needs at least 2 min to load/swap some stuff even if you see Hildon-Desktop. Then things are quite fast but you can use 500Mhz as minimum freq, modify transitions a bit and use boost mode if needed (see wiki). The only real issue we have at the moment with N900 and daedalus is Qt5 apps launch time. There is actually a workaround so, just ask here on TMO or IRC. (edit: ringtones break incoming calls ATM. As a workaround silent mode with or without vibrator fixes the issue) Note: if the UI is very slow or laggy, the culprit is the SDcard for sure, as now, things are really smooth on N900 with a good SDcard
