Into.the.Void.

One of the things that good Linux applications should have is uniformity. Just like Mac OS X does. All applications should use the same keybindings to perform the same tasks. For example, on _every_ OS X application, in order to quit it you have to press “CMD+Q”, it’s that simple and everybody follows it. Everybody. On Linux though there are some applications that simply don’t care about uniformity. One of these applications is smplayer.

While it is almost standard for Linux applications to quit using Ctrl+Q, smplayer simply doesn’t have this option. It has the option of closing the current video with Ctrl+X but it doesn’t have the simple option of quitting using a keyboard shortcut.

So, the next (oneliner actually) patch does simply what I described above. It makes smplayer quit using “Ctrl+Q”.

The screenshot that shows what the patch does:

smplayer-0.6.8-quit.patch:

+ quitAct = new MyAction(QKeySequence("Ctrl+Q"), this, "quit");
connect( quitAct, SIGNAL(triggered()), this, SLOT(quit()) );
openMenu->addAction(quitAct);

And a patched ebuild for smplayer-0.6.8 to use this minor patch (only one line is added to the ebuild):
smplayer-0.6.8-r1.ebuild

P.S. Keybindings in smplayer can be set through Preferences, and someone could actually put Ctrl+Q as the quit shortcut but I think that this should be the default setting like most other applications have it. Uniformity matters.

On my Macbook (4,1) I am currently using Debian with kernel 2.6.30-1-686-bigmem. This Macbook has Broadcom 4328 wireless chipset installed (02:00.0 Network controller: Broadcom Corporation BCM4328 802.11a/b/g/n (rev 03)) and unfortunately the necessary kernel module provided by Broadcom is pretty unstable. Or very unstable. Oh well…it’s totally unstable.

I had random freezes, usually when I first booted and tried to modprobe the module. After some searching around the net and a lot of experiments I’ve managed to create a kernel module that looks quite stable. At least I stopped getting any more lockups and freezes…To reproduce the module with the patches I’ve used follow the directions bellow step by step.

Find your kernel version:
mybox:~# uname -r
2.6.30-1-686-bigmem

Install kernel header files related to the kernel version you found (on the above example it is: 2.6.30-1-686-bigmem):
mybox:~# aptitude install linux-headers-2.6.30-1-686-bigmem

Remember to replace the version (2.6.30-1-6-bigmem) with the output of your mybox:~# uname -r

Create necessary dirs:
mybox:~# mkdir hybrid_wl
mybox:~# cd hybrid_wl

Download Linux drivers package from Broadcom:
802.11 Linux STA 32-bit Driver
(Driver info site: 802.11 Linux STA driver)
mybox:~/hybrid_wl# wget http://www.broadcom.com/docs/linux_sta/hybrid-portsrc-x86_32-v5_10_91_9.tar.gz

Download a few more patches from Archlinux and Gentoo:

mybox:~/hybrid_wl# depmod
mybox:~/hybrid_wl# modprobe wl

Check if everything loads correctly:
mybox:~/hybrid_wl# dmesg |tail

You can also chek the iwconfig output. Hopefully everything will be fine…
I hope this saves a few hours of searching and experimenting for some people…
