LCD: no more garbage

Finaly! I find out how to disable LCD without leaving garbage on it! It's time to polish my patches and send them upstream :)

I've used haret to capture gpio values.

Here's code to disable LCD sanely:

Access point with Raspberry Pi and rtl8192cu dongle

On Thursday ethernet ports (WAN and LAN1-4) in my Asus WL500GPv1 router have completely died, so I needed a replacement. Hopefully, recently I've got Raspberry Pi, so I decided to use it as a router. I've got TP-LINK TL-WN821NC USB stick from local store which is based on RTL8192CU chipset. Unfortunately, its driver doesn't work with vanilla hostapd, but requires patched ancient version of hostapd from Realtek . I'm using Archlinux on my rpi and I've found manual how to setup AP using this USB stick  here , but I don't want to overwrite binaries from repository packages, since it's not a sane way, and it can (and will) be broken by hostapd update. So I prepared a package, here's source package (just unpack it and build with makepkg directly on rpi), and here's binary package for armv6h (you can install it with pacman -U). I can't put PKGBUILD in AUR, since there's no stable hosting for Realtek's hostapd. If anyone is willing to host...

Migration to xubuntu

Recently I moved from kde to xfce on my laptop, but as xfce doesn't look pretty in gentoo (actually, it looks awful), I decided to move to xubuntu :) System is pretty fast now (much faster than it was in kde). Here's gtk analogs of kde apps I was used to: claws-mail (instead of kmail) exaile (instead of amarok) tilda (instead of yakuake) I've created ppa with some custom packages: tilda with changed shortcuts for switching tabs, default ctrl+pgup/ctrl+pgdn are used in mc and vim, so I changed them to shift+arrow, however it would be better to add option in gui for changing these shortcuts swt-gtk-3.5.2, it's required to fix rendering issues in tuxguitar Btw, there's arm toolchain in ubuntu repository :) xubuntu rocks!

Wayland and software rendering

Image
Recently I spent few evenings for hacking wayland . I like idea of wayland - rendering is done completely on client (in whatever way), compositor (server part) is responsible in rendering buffers from clients on the screen. Issue for me was rendering part of weston (reference compositor for wayland) - it uses GLES for compositing, but I want to try wayland and weston on devices without hw acceleration (pure software rendering), and running software GL on PXA270@312MHz does not sound like a good idea, does it? :) So I asked on #wayland@irc.freenode.org if it possible to implement software renderer, Kristian Høgsberg (khr) responded that in master branch of weston repo there's a nice abstraction of renderer, so it's possible to implement pixman renderer. So I did :) weston with x11-backend and pixman renderer khr and pq from #wayland were very helpful, and described place of renderer in wayland architecture, here're some points renderer just performs rendering of ...
