dropbox and browser

dropbox on Debian launches x-www-browser to open its website. Unfortunately x-www-browser is set for whole system and user can't change it. But he can choose his own preferred browser and then invoke it by invoking sensible-browser. Fortunately dropbox first tries to execute x-www-browser from its installation, and as there is no such file, falls back to executing /usr/bin/x-www-browser. So issue can be solved by:

# ln -s /usr/bin/sensible-browser /var/lib/dropbox/.dropbox-dist/x-www-browser

One can set preferred browser by setting up evironment variable BROWSER (in .profile or .bashrc, for example).

Add current directory to GTK+ file open dialog

Now GTK+ file open dialog offers no way to open file from current working directory. One can find recent documents, home directory or some other bookmarks. Quite frustrating when you know for sure where file you need is, but forced to traverse directory tree to current working directory.

Recently I found workaround. Solution is to add /proc/self/cwd as bookmark. Unfortunately path will be displayed as /proc/self/cwd, not actual cwd, but anyway, it works!

CX_Find_Cell_With_Point and 3ddp (Fluent)

There is a function CX_Find_Cell_With_Point. It's not listed in official documentation but it works well when you need to find a cell which contains specified point. Otherwise one must use very slow dumb search or develop  some sofisticated search algorithms. But there is a glitch with its use. As it's undocumented, there is no guarantee that it even compiles.
`CX_Find_Cell_With_Point' does not work with double precision (3ddp) Fluent solver!
That's true for Fluent 6.2.16 on lnamd64 (at least). With 3ddp it always returns NULL.

And if you're here for example, here is a code:

#include "udf.h"
#include "surf.h"
#include "para.h"
 
void some_function()
{
    cell_t c;
    Thread *t;
    CX_Cell_Id cx_cell;
    CX_Cell_Id *cx_cell_ptr;
    real pt[3];
 
    CX_Start_ND_Point_Search(); /* call this before actual search */
                                /* perhaps it'll do some initializations */
    for (k = 0; k < 1000; k ++) {
        /* fill pt[3] with data */
        pt[0] = 0.0; pt[1] = 0.0; pt[2] = k / 1000.0;
 
        /* perform search */
        cx_cell_ptr = CX_Find_Cell_With_Point(pt);
        if (cx_cell_ptr) {   /* function can return NULL if no cell was found */
            cx_cell = *cx_cell_ptr;
            c = RP_CELL(&cx_cell);  /* get cell number */
            t = RP_THREAD(&cx_cell);  /* get cell thread */
 
            /* ... do your calculations ... */
 
        } else {
            /* no cell was found */
        }
 
    }
 
    /* It's a good practice to clean up */
    CX_End_ND_Point_Search();
}

XKeysymDB

Someday upstream developers decided to remove XKeysymDB from libx11-data. But there still old (motif-based) applications exists that relies on that file. In my case application ignored any input from keyboard making it impossible to use it anyhow.

Linux on Clevo E4105

I'm currently running Debian Wheezy (testing) on Clevo E4105. Almost everything works out of the box. Although there was some quirks with hardware with previous kernel versions.

Kernel 2.6.39 and older missed support for wireless network card (RTL8192SE, identified by lspci as RTL8191SEvB). The driver from official site has bug in power saving code which resulted in random hangs. Cleaned version included in kernel 3.0 works well. Somewhere in 3.1, same bug was introduced. But 3.2 is ok again.

Other hardware, webcam, cardreader, ethernet NIC, dvd-rom, sound, usb controller works out of the box. I haven't tested modem or HDMI output, but some version of Ubuntu LiveCD asked me if I want to install proprietary driver for modem. And xrandr output implies that HDMI support exists.

Screen is 14" size with 1366x768 resolution (which is 112 dpi). View angles are terrible, as one can expect from TN screen, and it's a bit bluish.

Platform keys (those with Fn+something). Volume up/down/mute, play/pause, video switch, sleep button, all produce ACPI events, while touchpad disable, screen off/on, webcam on/off, wireless on/off works on lower level (I think, firmware). Unfortunately brightness can't be changed with keys as they produce no effect. Brightness itself can be changed via `xbacklight` or by writing to /sys/class/backlight/acpi_video0/brightness.


Here is lspci output:
