Gemini PDA - Linux / Gnome Shell

« on: June 26, 2018, 10:35:41 am »

I've been using Gnome3 as my desktop for a couple of years now and I'm quite happy with it. Previously I'd always been a make-it-look-as-much-like-windows-xp as possible type and only decided to put some effort in to move from Mint to Ubuntu with Gnome when I got a laptop with a touch screen. Gnome was reckoned to be the most touch friendly option at the time.

I almost never use the touchscreen but I'll happily stick with Gnome at this point regardless.

I didn't hold out much hope but today I thought I'd try Gnome Shell to see if it was even barely usable on the Gemini hardware. This might save me some pain adapting to a new interface.

Predictably it was waayy toooo sloooow.

Worth a try though. Just thought I'd share.

PS, if you'd like to try yourself then go ahead:

[div class=\'codetop\']CODE[/div][div class=\'codemain\' style=\'height:200px;white-space:pre;overflow:auto\']sudo apt-get install gnome-core[/div]

You will find it automatically installs gdm3 and sets it as the default display manager. This does not work properly (lets you log in but presents a grey screen only after that) so go back to the previous LXDM display manager:

[div class=\'codetop\']CODE[/div][div class=\'codemain\' style=\'height:200px;white-space:pre;overflow:auto\']sudo dpkg-reconfigure lxdm[/div]

Then you can select Gnome in the session dropdown.

Gemini PDA - Linux / Debian virtual consoles and F1 - F12 keys in general

« on: June 25, 2018, 12:52:34 pm »

key <AE01>  { [         1,      exclam,          bar,    F1 ] };
    key <AE02>  { [         2,    quotedbl,   numbersign,    F2 ] };
    key <AE03>  { [         3,    sterling,    backslash,    F3 ] };
    key <AE04>  { [         4,      dollar,     EuroSign,    F4 ] };
    key <AE05>  { [         5,     percent,         less,    F5 ] };
    key <AE06>  { [         6, asciicircum,      greater,    F6 ] };
    key <AE07>  { [         7,   ampersand,  bracketleft,    F7 ] };
    key <AE08>  { [         8,    asterisk, bracketright,    F8 ] };
    key <AE09>  { [         9,   parenleft,    braceleft,    F9 ] };
    key <AE10>  { [         0,  parenright,   braceright,   F10 ] };

So, FN+SHIFT + (1,2, ... ) will access F1, F2, etc.
I've tested only F5  in browser to refresh page, and works like a charm.
So to access console CTRL ALT F1 ( would  have to press CTRL ALT FN SHIFT and 1 keys ). I've tested here but it didn't work.
I think you will have to change  some configurations.
Unfortunately I am very busy to investigate this. Maybe this I had wroted may help.
Good luck.

Thanks galodoido.

It doesn't work for me either and now my fingers are all tangled in a knot!

Gemini PDA - Linux / Debian virtual consoles and F1 - F12 keys in general

Hi,

I want to switch out of graphical to a virtual console (useful when things stop responding for whatever reason). On your average PC this would usually be achieved with ctrl + alt + F#.

So how do I do this using the Gemini keyboard?

Cheers

Gemini PDA - Hardware / Wired headphones. Faint buzzing/scratching noises

« on: March 27, 2018, 04:56:42 am »

Based on an identical fault with my Dell XPS13 9350 my money would be on a power saving feature turning off some noise suppression circuitry in the sound device.

I posted about this previously (but not very helpfully) but this time I'll add a useful link:

https://wiki.archlinux.org/index.php/Dell_X...sing_headphones

Which may be helpful for linux users but turning off that power saving may reduce battery life.

Don't have my Gemini yet so can't confirm but I'll want to get this sorted as soon as I do.

Gemini PDA - Hardware / Noise when not playing audio

« on: March 20, 2018, 08:51:24 am »

There's been a lot of comments on Indiegogo re electronic noise getting onto the headphone output when audio is NOT playing.

I'm a long way off from getting my Gemini so can't do any proper investigation yet but I would like to share my experience of an identical problem with a different product.

My Dell XPS13 had this problem of clicks, wizzes and beeps when it should be silent (running Linux).

Turned out this happened when the sound card entered a power saving state almost immediately after finishing playing (emptied the buffer). I suspect that at that point, parts of the circuitry are powered down and any electronic balancing/noise reduction techniques ceased to function.

The fix was to disable that power saving feature, incurring a very minor battery penalty.

I would suggest that is where folks go looking for a solution with the Gemini first, although a battery penalty might be more severe with a smaller device so it might be something that's worth living with.
