HDMI + Touchscreen??

Hi
I have a RasPi 3 connected to the official 7" touchscreen.

Is it possible/practical to have a monitor connected to the HDMI port at the same time as the touchscreen ribbon cable is attached?

Thanks

Re: Other submenu item

Hi Thanks for the reply, but wow, it's complicated! I shall have to sit down and study it. It still doesn't answer my questions as to why a load of entries have appeared in the "Other" menu", not at my behest and trying to find them and get rid of them is like looking for a needle in the proverbial ...

Other submenu item

Hi I have a RasPi 3B. The other day, I added a menu item to run a program of mine, by copying its desktop shortcut to /usr/share/applications. It duly appeared under a new submenu item, called other. It was the sole entry. Since then, I have installed various software and other now has loads of item...

Re: GPS problems

Hi My earlier post indicating how I had solved the problem was wishful thinking! Everything was fine until I did an update/upgrade, when, hey presto, the problem returned! Earlier, you hadf asked me whether gpsd was running. I issued a killall gpsd and it made no difference. Today, I looked in task ...

Right click, raspi touchscreen, Buster

Hi I have a RasPi 3B with the official 7" touchscreen. I have been trying to find out to "right click" with my digit. I found TwoFing, but installing this got rid of my desktop altogether!! Is there a method which will work with Buster please? "Double-clicking" is also hopeless! Even trying to alter...

Re: GPS problems

Hi again Well, I have cured the problem but I don't know why! On a whim, I edited my gps.c file, changing ACM0 to AMA0 and recompiled it. It ran fine with ./gps. I got garbage from it but so what? I then re-edited gps.c back to what it was and recompiled. Now, it runs with ./gps, sudo no longer requ...

Re: GPS problems

Hi
Thanks for the reply.

There are 2 entries with dialout, when I do ls -l /dev/tty*, ACM0 and AMA0:

crw-rw---- 1 root dialout 166, 0 Nov 14 22:50 /dev/ttyACM0
crw-rw---- 1 root dialout 204, 64 Nov 14 13:07 /dev/ttyAMA0

Re: GPS problems

Hi Thanks for the reply. I killed GPSD but it made no difference. It seems to be a permissions thing as sudo ./gps works, whereas ./gps gives the error message. I have another RasPi and ./gps works fine on that. I did a ls -l /dev/ttyACM0 on each machine and the permissions on both are crw--rw---- B...

Hi Yesterday, I plugged a u-bloc gps dongle into my Raspi 3. It appeared on ttyACM0 and worked fine. Today, things have changed!

Re: Bluetooth transmiision?

Hi It works! I had simply followed the instructions = that's why it didn't work!! It doesn't seem a very well thought out part of the OS though! Strangely, it shows input and output as the speaker! Surely, the speaker is output only? All I need to find out now is how to push the play icon on the web...

Hi Thanks for the replies. I now see that fonts appear to be a minefield!! Where and how do I install fonts at the system level? As I said, i downloaded some fonts and placed them in /home/pi/.fonts. In the TLabels font list, they appeared and I selected the one I wanted. I have another RasPi also w...

On the Pi, I am running my application, which, amongst others displays the time, date etc. The time digits are dislayed in TLabels. It is in these labels that I have chosen a new font.

Re: Font Problems

Hi
Thanks for the reply.

They are true type 7 segment fonts.

Yes, they work in Libre-Office.

Yes, I do use SSH, but the tresults are just the same when I run the program directly.
No, there aren't any error messages at all.
I am baffled!

Hi, I recently installed some new fonts on my RasPi 3. I put them in /home/pi/.fonts. After this I used fc =cache -v -f to update things. I then rebooted the Pi. I then went into lazarus to change some fonts in my program. The new fonts showed in the list and I made changes. On running the program f...
