Comment on Marin Bobcat Trail bike maintenance by Philip Withnall

Thanks (both of you!) for the helpful responses. I’ve used both Sheldon Brown’s site and techdocs.shimano.com (which was invaluable when re-adjusting the rear derailleur). I’ll have to take a look at the books you recommend.

Unfortunately I couldn’t use the cable tie trick for the rear hub, as the balls were loose rather than in cages, and the rest of the rear hub was trivial to reassemble. Oh well.

I'll repeat the endorsements for sheldonbrown.com and techdocs.shimano.com. Also, the Park Big Blue Book is pretty good for general maintenance.

One tip I've seen for dismantling hubs is to string the parts onto a cable tie as they come off, so you can put them back on again in the right order. I may have spend two hours putting a hub back together because I managed to knock the tray holding the pieces.

The Haynes Bike Book was a bit of a bible for this kind of thing. For any Shimano parts you can get both assembly instructions and service guides with nice exploded diagrams for everything they have ever made from techdocs.shimano.com. Looking at your (nice) diagrams even if the Marin has generic components, the design is the same as Shimano. You don't need to record the exact cable outer lengths - the stock outers are usually generously proportioned (for ease of assembly, not optimal braking/shifting) anyway. I'd use blue loctite on remounting the brake studs in the frame, you don't want those coming loose. And I guess you've already found sheldonbrown.com... Sounds like you had fun doing this and learned a lot, keep it up!

Comment on Weston frame buffer backend by Philip Withnall

If your GPU can do OpenGL ES, and has DRM and GBM drivers, then you should use Weston’s DRM backend. The fbdev backend is only really intended for systems which don’t have hardware acceleration (or suitable drivers). The call to eglInitialize() is in Weston’s DRM backend, not its fbdev backend. fbdev doesn’t use EGL at all.

You should probably visit #wayland on Freenode. There are people there far more knowledgeable than me about EGL.

Hi Philip What is the reason that this can't work with OpenGL ES? I have an ARM Chromebook from Samsung, and this has an fbdev driver. I'd really like to run Weston on this thing with OpenGL ES acceleration. Would you happen to know what it would take to get this to happen? I've fiddled with it a bit, and I can see that it's the call to eglInitialize() that fails when it's run on a separate VT. As far as I can see the OpenGL ES library for the Mali T-604 supports EGL, the kernel has DRM, and I think it supports KMS as well (VT switching is fast, perhaps a 0.5 second delay). Do you know why it doesn't work?

It comes with Weston: http://cgit.freedesktop.org/wayland/weston/log/data/pattern.png

Correct, the frame buffer backend uses pixman for rendering. Weston is fairly complete, but I don’t know if anyone’s using it as their main compositor at the moment.

With this Weston doesn't need hardware accel to work, right? Also, how complete is Weston at this point?

Where can I get this wallpaper?
