HOWTO: Install basic G15Tools support for the Logitech G15

[serge lorich]

good day to all of you again.

toying with libg15render's sources i made UNICODE support for it.
solution is not too beautiful but it works with my cyrillic fonts without any additional actions from user.
output from console thru Composer works rightly...

if Render's authors are interested in this fix, please contact me.
my questions on sourceForge are not answered.

[Aneurysm9]

the next questions.
* while testing g15composer i found one issue. g15composer falls when i load bitmap to the same slot three times. maybe it is possible to free previously alloc'ed memory?
* the second question is about internationalization in g15tools. i mean utf-8 support for TTF fonts.

I'll take a look at the g15composer issue, I probably did forget to free memory somewhere. Can you get a backtrace when it fails or provide more detail on how it fails? As for internationalization, I don't have any experience doing that sort of thing, if you do I'd be greatly appreciative of patches.

Just saw your post that you have UTF8 working. I'd love to see the patch. Sorry for not responding sooner, I've got another project that I'm actually being paid for (and, thus, the payor's expectation of quick results) that's taking most of my time now. There are a couple of other minor fixes for libg15render that need to get pushed out too, so if you can get a patch to me this weekend, I'll see if I can get a new release out quickly.

Hello people,

Is there any amd 64 bit support for the G15?
I'm on Kubuntu 6.10 Edgy.

Thanks!
MachineHead

Yes, I posted them some pages back. I'll have a look for it in a bit and I'll edit this post.

Did you even look for them? Two pages back I posted the debs
http://ubuntuforums.org/showthread.p...64#post2236531

Howto: Compile the necessary debs in Ubuntu (7.04, probably the others as well)

download all the necessary files at sourceforge to your desktop here and here

You want g15composer, libg15, libg15render and g15daemon. The rest is optional, play with them once its all working.

Lets take care of dependencies:

sudo apt-get install build-essential libfreetype6-dev libdaemon-dev libusb-dev libttf-dev checkinstall

temporarily take care of uinput:

sudo modprobe uinput

(Once this is all working make sure to type sudo nano /etc/modules into a terminal and put uinput at the end of the file. This will ensure it loads automatically on boot)

extract all the archives onto your desktop (right click, extract)
(or in terminal type tar -xf *name archive*)

and run the script, check for errors directly above the step "create default documentation" in between compilations to make sure your dependencies are ok. When it asks you to name the package simply type in the full name, libg15-1.2.2 for example and it will fill in the details:

for package in libg15-1.2.2 libg15render-1.2 g15daemon-1.2.7 g15composer-3.1; do cd $package; ./configure --prefix=/usr --enable-ttf; make; sudo checkinstall make install; cd ..; done

Please, use a little common sense when it comes to the version numbers. Just check to make sure the folders on your desktop match the version numbers in the mini-script above.

Follow the above steps and you should have built all the packages with ttf support, try typing sudo g15daemon and a clock should pop up.

If you want to have the daemon autorun on startup try running (BE CAREFUL)

sudo visudo

Change the user part and add the following to the end of the file:

user ALL= NOPASSWD: /usr/sbin/g15daemon

and press ctrl+x to exit. Press Y to accept, it will check for syntax mistakes and if it finds one it will ask you "What now?" Simply press E and make the necessary changes.

After this go to System->Preferences->Sessions and add sudo g15daemon to the list

And if you really, really can't figure it out I attached the compiled debs for 7.04 386

Ps. I take no credit for the above mini-script, I simply found it somewhere and find it extremely useful. Thanks to whoever made it.

Edit:

Also attached is a script for amarok, save it to you Desktop. Now simply open Amarok -> Tools -> Script Manager -> Install script -> select amarok-g15-dcop_cli.pl.amarokscript.tar.gz -> install -> run it from the list (its under general). It should work immediately if you had g15daemon running (the clock).

Hi there drdnl,

Thanks for your reply.
I didn't search the pages by hand no.
I googled for g15 drivers and found this thread.
Just couldn't find any mentioning about amd 64 architecture.

Thanks for your reply, I'll remember to flip a few pages in the future.

btw, isn't i386 32-bit architecture?
It's my first go on Kubuntu so I'm pretty impressed I got most of what I need set up at the moment

I'll work on my keyboard later, for my work concerns me at the moment

Regards,
MachineHead

[drdnl]

You're welcome,

Just to be clear, the 6.10 amd64 debs are two pages back. The debs I just posted are indeed i386 for 7.04, if you need 7.04 you can compile them with the above.

Hang in there, Linux is absolutely worth the learning curve (1 year and still a happy ubuntu user). I now use my pc in ways which were practically impossible before and have learned alot in the meantime.

Good luck and feel free to post if you have problems,
D

[Spartan.II.117]

alright, i need a little help here. i installed the 7.04 debs in the above post, but i cant seem to get g15composer to work properly i've tried the mkmod to create a pipe, but it still holds the command line until i use ctrl+c to exit it manually, an i missing something? also i'm trying to figure out how to build a scxript to work with exaile, so if i could get some info about interacting with g15 composer that wouls be great.

Here is a possible fix for the repeating macro issue. The problem occurs when HAVE_X11_EXTENSIONS_XTEST_H is true and is caused because the last character that is pressed never sends the release to X11.

I modified my g15macro.c to always record a key release (but only display it for the special keys). Your mileage might vary and I have only tested this for a short while, but it seems stable enough...

I followed the directions in http://ubuntuforums.org/showthread.php?p=2461304
to get the g15daemon running using the 1.9.0 pre 2.0 version of g15daemon.

void xkey_handler(XEvent *event) {

    static unsigned long lasttime;
    unsigned char keytext[256];
    unsigned int keycode = event->xkey.keycode;
    int press = True;
    int display = True;

    if(event->type==KeyRelease){ // we only do keyreleases for some keys
      pthread_mutex_lock(&x11mutex);
      KeySym key = XKeycodeToKeysym(dpy, keycode, 0);
      pthread_mutex_unlock(&x11mutex);
        switch (key) {
            case XK_Shift_L:
            case XK_Shift_R:
            case XK_Control_L:
            case XK_Control_R:
            case XK_Caps_Lock:
            case XK_Shift_Lock:
            case XK_Meta_L:
            case XK_Meta_R:
            case XK_Alt_L:
            case XK_Alt_R:
            case XK_Super_L:
            case XK_Super_R:
            case XK_Hyper_L:
            case XK_Hyper_R:
                break;
            default: 
                display = False;
                break;
        }
        press = False;
    }
    if(recording){
        current_recording.recorded_keypress[rec_index].keycode = keycode;
        current_recording.recorded_keypress[rec_index].pressed = press;
        current_recording.recorded_keypress[rec_index].modifiers = event->xkey.state;
        if(rec_index==0)
            current_recording.recorded_keypress[rec_index].time_ms=0;
        else
            current_recording.recorded_keypress[rec_index].time_ms=g15daemon_gettime_ms() - lasttime;
        rec_index++;

        /* now the default stuff */
        pthread_mutex_lock(&x11mutex);        
        XUngrabKeyboard(dpy,CurrentTime);
        pthread_mutex_unlock(&x11mutex);

        if(display == True) {
           fake_keyevent(keycode,press,event->xkey.state);
        }

        pthread_mutex_lock(&x11mutex);
        XGrabKeyboard(dpy, root_win, True, GrabModeAsync, GrabModeAsync, CurrentTime);
        XFlush(dpy);

        strcpy((char*)keytext,XKeysymToString(XKeycodeToKeysym(dpy, keycode, 0)));
        pthread_mutex_unlock(&x11mutex);        

        if(display == True) {
           if(0==strcmp((char*)keytext,"space"))
               strcpy((char*)keytext," ");
           strcat((char*)recstring,(char*)keytext);
           g15r_renderString (canvas, (unsigned char *)recstring, 0, G15_TEXT_MED, 80-((strlen((char*)recstring)/2)*5), 22);
           g15_send(g15screen_fd,(char *)canvas->buffer,G15_BUFFER_LEN);
        }

    }else
        rec_index=0;

        lasttime = g15daemon_gettime_ms();
}

Also, I moved the save routine to write out the configuration every time a new macro is recorded.

void *Lkeys_thread() {
...
                default:
                    if(keystate >=G15_KEY_G1 && keystate <=G15_KEY_G18){
                        if(recording==1){
                            record_complete(keystate);
                            recording = 0;
                             pthread_mutex_lock(&x11mutex);
                             XUngrabKeyboard(dpy,CurrentTime);
                             XFlush(dpy);

                             /* Write configuration every time a macro is recorded*/
                             config_fd = open(configpath,O_CREAT|O_WRONLY|O_SYNC,0600);
                             write(config_fd,mstates[0],sizeof(mstates_t));
                             write(config_fd,mstates[1],sizeof(mstates_t));
                             write(config_fd,mstates[2],sizeof(mstates_t));
                             close(config_fd);

                             pthread_mutex_unlock(&x11mutex);
                        } else {
                            macro_playback(keystate);
                        }
                    }
                    break;
            }
            keystate = 0;
        }
    }
    return NULL;
}

Now that I've upgraded to feisty I installed the g15daemon again and everything went fine but I couldn't get libg15render to install with -enable-ttf.

I had the g15daemon running with amarok and ttf enabled before in dapper and didn't have any problems. Does anybody have any ideas what could be causing this error?
