So I've no idea where to go to change the setting.

Optimising for readability tends to be an iterative process. One simple starting point is:

menu > desktop > chtheme gtk/qt theme chooser

Bottom left you will see a font button. You can increase font size or select a bold font (or both).

If JWM fonts are a problem you will need to edit /root/.jwm/jwmrc-theme by hand. Bump up the numbers until you get something easy to read

Most applications will have their own function for changing font and font size.

Don570's suggestion is perfectly sensible but it involves putting your screen into a lower resolution. Something that you may not want since it impacts other functions such as video playback.

You don't need to edit config.txt offline. Just mount the boot partition and use a text editor. The changes will not take effect until you reboot.

Although making multiple bespoke changes is tedious it will eventually give you a better result that trying to find a global trick that changes everything in one go.

@amj:

1. "menu > desktop > chtheme gtk/qt theme chooser

"
Understood.

2. "If JWM fonts are a problem you will need to edit /root/.jwm/jwmrc-theme by hand. Bump up the numbers until you get something easy to read
Most applications will have their own function for changing font and font size.
"
Understood, but I was hoping to avoid the necessity of doing it this way.

3. "Don570's suggestion is perfectly sensible but it involves putting your screen into a lower resolution. Something that you may not want since it impacts other functions such as video playback."
OUCH!
Pity about the negative impact on "other functions such as video playback".

4. "You don't need to edit config.txt offline. Just mount the boot partition and use a text editor."
I find it easy/easier to make the edits on my PC.
Which is the boot partition?
The 2nd/larger one holding the OS?

4. "Although making multiple bespoke changes is tedious it will eventually give you a better result that trying to find a global trick that changes everything in one go."
Pity about this.
I've tried to make "bespoke changes" in the past, and found these inadequate because only some things were improved, and others not.

Each suggestion and point of view increases my mental picture/understanding of things.
Getting closer to the point where I should act.

Pi 3 Wireless Issue

#590 Post by blackcorvo »

For anyone trying to get Raspberry Pi 3's Wireless to work on Quirky, try the following:
Using BerryBoot, go to Edit Menu, then set up your wireless connection from there. Once it's connected and working, exit and start up Quirky.

I was able to make mine work that way!

a1. Searched for "hdmi_group=".
Found 2 that had numbers on the end, but only the 2nd came after a single hash [commented settings came after a double hash] as follows...
#hdmi_group=1
Can you confirm I should change this to....
#hdmi_group=4
EDIT:
I made a mistake the numbers should be exchanged --->

Code: Select all

hdmi_group=1
hdmi_mode=4
There is some problems with video playback using Barry's video app
but try various settings such as half video frame size.

I fail to understand what this means.
Which number[s] should be exchanged for which?

One thing that has not been mentioned in this thread: Newly installed QX814 leaves the RPi video memory at the default 64Mb. Anyone wanting to make serious use of the RPi for video playback should bump the GPU memory up to 128Mb with a gpu_mem_1024=128 instruction in config.txt.

In addition it pays to use menu > system > wcpufreq CPU scaling tool to ensure that the ondemand governor is enabled with (I suggest) a 50% threshold. Also use menu > system > bootmanager configure bootup to ensure that the wcpufreq service is automatically activated during system startup (by default it is off).

I'm running QX814 on both RPi2 and RPi3 and have been interested to see that a wide range of video files will play back OK on the RPi3. The RPi2 is more prone to performance issues.

My "config.txt" file [read on my PC] includes only a single line that includes "gpu_mem_1024=" as follows...
#gpu_mem_1024=944
What should I do to that?

We don't know the exact details for your 'Sony Bravia 32 inch smart TV' so we can't tell you the optimal settings. Read the Sony documentation to find out the full range of capabilities your TV has and then read through the explanatory text in the video section of config.txt

In addition there is online help at:

Code: Select all

https://www.raspberrypi.org/documentation/configuration/config-txt.md
http://elinux.org/RPiconfig
http://raspberrypi.stackexchange.com/tags/config.txt/info
Don570 suggested running your TV at a lower resolution than the default. That will automatically have the side-effect of making the text on the screen larger. The Sony documentation should tell you the range of options you have and the config.txt parameters provide the means to select between those alternative options.

Remove the # and change 944 to 128.

:oops:
I should have exchanged the numbers...

Code: Select all

hdmi_group=1
hdmi_mode=4 
This will make the screen easier to view if you have a viewing problem.

This made an improvement = the items on screen are now increased in size, but not by enough.
I can only just read them from about 6 or 7 feet.
Need them even bigger so I can read them from say 10 to 12 feet.

hostapd

#599 Post by Dud »

I recently used hostapd from (iIrc) ubunti xenial universe.
I'm trying to build a cleaner system from scratch in the light of experience but hostapd seems to have gone from the ppm.

Ideas?

Tia, Cheerio.

hostap works with rasiPi? cool if you did not erase prior install packages are stored under file sub-folders. Should be a way to point to local copies but never had time to figure out how. If you made this work I would like to know how to as well. want to be able to vnc into RaspPi host as a standalone wifi so I can control it with my cheapo kindle fire ( can not buy a 7in display for RiPi as cheaply as a that device ) :wink:
Do need to lock down RiPi wifi since this is going on public buses / trains and the like.

Made these 2 changes, BUT although...
I think there may have been a slight increase in the size of some stuff...
e.g. The text in the right-click menu is bigger than in the bottom-left menu...
I am unable to detect any significant increase in the size of on-screen items.
So they are still not big enough. :(

2. My wife uses, in Windows...
a. To magnify the displayed items on screen: ctrl+alt+]
b. To diminish the displayed items on screen: ctrl+alt+[
You blip the ] repeatedly to increase in steps, or hold to zoom up.

Anything like this in Puppy?
