I have a Raspberry Pi Model B version 2 that I tinker with for amusement. Recently I dug it out after sitting a year or so and loaded the SD card with Raspian Jessie Lite. The Lite package as it turns out doesn't include X, so I've been adding it by installing some X programs I want with apt-get and letting it fill in the dependencies. There apparently isn't a clearly defined method for adding X to Lite, which is mostly for headless use. Most of the BSDs are packaged with X in a few packages you install in addition to the OS if you want it. When I added the xinit deb I was able to use startx. I have an ongoing thread on their forum in the troubleshooting area: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=145665&p=960571#p960571 and somebody said I should also install the raspberrypi-ui-mods deb which helped quite a bit but I still have strange things happening.
Different programs seem to run at different color depths. Gimp, Iceweasel (Firefox), a few others can open photograhs in what looks like normal 24 (or 32) bit color. Other programs like Synaptic and qiv seem limited. Qiv shows photos as a black image, Synaptic comes up with a black panel and white text on it. The Pi works with a framebuffer apparently instead of a real video card. I think it's shared memory between the GPU and the CPU. If I do X -configure I get an error that there are no devices to configure and it lists video drivers fbdev and modesetting. I seem to have both installed. If I run xrandr it fails to get the size of gamma. If I run xdpyinfo I see that the root window has a depth of 16 planes. I see lots of visuals, most of the Truecolor class, toward the end of the list are some DirectColor. Most of these are 16 planes, 6 bits per colot. But at the end is one with 32 planes and 8 bits per color. It's X server 1.17.2, I don't see any errors in Xorg.0.log except things like missing font directories. I guess my question is what's still missing. To some degree if they're interested I'd like to help raspberrypi.org create a package for adding X to the Raspian Lite distribution (or improve raspberrypi-ui-mods). The alternative is a “full desktop” package with Libre Office, Mathematica, many other things. It's a 290 meg download vs a 1.3 gig one. I'd like to see an addon to lite to get basic X with less featureitis. -- Credit is the root of all evil. - AB1JX _______________________________________________ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
