Intel graphics and other stuffs

December 30, 2008 Leave a comment

Arch got a kernel update,  kernel26 and xf86-video-intel is at 2.4.3-1. This seems to have fixed the issue with the TTM buffer manager in glxgears somewhat. I now get a fps of around 350, which is way better than the earlier 62fps.

However, the lag is visible just using xcompmgr along with xmonad. Transparnet urxvt seems to have problem displaying more than a couple of pages of scrolling text. Hopefully, the next update will improve it. 🙂

Transparent terminals are probably useless but still somewhat beautiful looking for an otherwise dumb tiling WM.

Yaourt broke due to some update in the AUR website, although its been fixed now. Just enter this command to update yaourt,

yaourt -S yaourt

simple, ain’t it? I just use arson though. Somehow I like to manually do a makepkg and pacman -U 🙂

Starting wireless from the terminal

December 21, 2008 3 comments

Wicd has always been nice to me 🙂 However, there are times when I don’t need X, and so I manually up the wireless using ifconfig and iwconfig. The Arch wiki suggests that I use network profiles along with netcfg. Its nice but for a simple dhcp or a static IP one shouldn’t have to install another app.

It was then that one user in #archlinux gave me a script to bring up the wireless interface with a simple script in rc.d. Pretty simple, clean and plays along nicely with Arch’s KISS principle I would say. I changed the dhcp to static (yes I use it at home only, so no need for dhcp at the moment), and there she comes up precious. 🙂

The usage is a simple /etc/rc.d/wifi {start|stop|restart }

No more typing in a thousand things, and I got a nice Arch way of doing it. For anyone interested, I dropped it in here, just grab the wifi file and place it in /etc/rc.d/ and offcourse make it executable.

Xorg7.4 brings input hotplugging and new intel drivers

December 20, 2008 Leave a comment

The recent update in the Xorg package broke the settings for quite a few people. Xorg7.4 brings with it input-hotplugging, meaning that input devices are now detected by hal dynamically as and when they are added. Hence, the good old /etc/X11/xorg.conf now needs to be modified to be used with the new evdev driver.

Keyboard, touchpad, mouse, etc are now to be configured in hal policies, in arch its located here, /etc/hal/fdi/policy/. The wiki entry describes in detail the whole process. Offcourse you can just disable the hotplugging feature altogether, by adding the following in the xorg configuration,

Section "ServerFlags"
Option "AutoAddDevices" "False"

Along with the change in input device configuration, the new Xorg also brings us the new intel driver, which also replaces the i810 driver for intel chipsets. And voila, glxgears no more shows the usual framerate, instead the refresh rate is displayed. It also displays an error regarding the “TTM buffer manager”, which is supposed to be fixed with the arrival of the linux 2.6.28 kernel.

So, those of you who haven’t updated their system yet, take a look around and edit the X configuration accordingly before you restart X and get into a situation where neither your keyboard or mouse works.
