Who me? I haven’t even tried yet, I just looked up some pi fast boot stuff before learning about Realdash, but I want to say you can see boot times in the sun 10 second range easily, sub 6 may be tricky.

Having to boot to the desktop is the time killer, though. Booting to CLI is what you can get done fast. ---

Dietpi Success. Both Xfce and LXDE. Not only that it looks like it’s running pretty smoothly. I can only judge it based on the opening animation at the moment. Haven’t hooked it up in my car yet.

Rasbian is too laggy. I’m trying to install this in my car as my dash. I have an Android tablet in there now, but it overheats easily and it doesn’t automatically turn on/off with the car. It used to, but Google changed something with one of the updates which seems to block this. Plus, I’ll be able to plug directly into my ECU via CAN instead of Bluetooth. The tablet refuses to charge and connect via usb. I originally tried to get it running without a desktop gui, but as realdashdev stated, that isn’t possible at the moment. Hopefully, the team can get that worked out as it’ll make this boot up quickly and have more resources available. ![fkCIFdnR28hBEjl0_8O6mijSTLAPKPZgJA24NzuxP9FJIuaGMUCmZrumXvcJWuI6TzI0KSnkqN-4m93ksqokxU9IxhTgUQgaAauFzwDqAm57IlYnPSqAHoDypNxyFI2Nc_0TAmYnutDkjoxCDebb4sU__dwprebBPWK8VmMizMjvBj7SBeKUUjPcJlTv9s91-nrLZNRKr13bZhpUAKKxGeGgQDfGdloN.jpeg](https://forum.realdash.net/uploads/default/original/1X/2281048f45cd6cf9595680532c7bb8b7ff43fdc8.jpeg) ---

Got it booting straight into Realdash. I ended up adding .xsession under the user account. Below is the code. Unfortunately, it’s not saving my settings. It does remember my login, but I have to log in each time. I also don’t have a mouse cursor, but I’m pretty sure that’s because I didn’t call it out in xsession. Also, it looks like none of the folders for a user is included with a Dietpi image. That could be a reason why it’s not saving. Youtube video of the boot.

Got it figured out. DietPi really restricts users. I found in the xsession logs that it couldn’t create any of the folders. I created the main folder /home/psedog/Documents/Realdash Then all of the subfolders camera, datalogs descfiles, dyno, settings, tripdiary I also fixed all the permissions as the user didn’t have permissions… So odd. Note: if you want to exit realdash and go back to the command prompt, just hit Esc. I have other projects around the house at the moment (Honey Do’s), so connecting it in the car will come later. [https://youtu.be/9USYzIptwdA](https://youtu.be/9USYzIptwdA) Edit: I have fixed the curser and gotten rid of xsession commands that didn’t work and/or weren’t required. It now takes just over 20seconds from applying power to opening. Now, the question is how to activate the full version? I purchased it on Google’s app store. Do I need to buy a subscription now? ```plaintext xrandr --fb 1280x800 xsetroot -cursor_name left_ptr realdash ``` ---

Did you have to install a desktop manager or do you run without LXDE or XFCE? ---

> [@](#): > > Did you have to install a desktop manager or do you run without LXDE or XFCE? You have to have a desktop environment installed. We are using that environment here, but not the whole desktop. Note: I tried this method with Raspian, but it was still sluggish. DietPi seems to be the best option for Raspberry Pi. ---

Alright. So, I figured out how to get this working on Raspbian. It’s smooth and no longer has permissions issues. I’m not going to upload an image. That would get out of date quickly and I’d be redistributing software. Not my lane 🙂 I did create a Github. All the instructions are there. Raspi settings are the same as the first post in this thread except for the GPU memory. [https://github.com/psedog/Raspi-realdash](https://github.com/psedog/Raspi-realdash) If you have any suggestions or issues, let me know. Working through this with you. Notes: I wanted to have my script enable the graphics options, but haven’t figured out how to do that reliably yet. Also, Raspbian defaults to 64MB for GPU memory. It seems to be running smoothly this way. Edit: Occasional crash in the garage. I’ve changed the GPU memory to 128. Edit 2: Still an occasional crash in the garage. I don’t think it’s the video memory. ---

I followed your tutorial, but I was only able to add the files through the Raspberry OS itself, on windons I couldn’t access the SD card folders. I changed the resolution in the xsession file to 1920x720 to use ultrawide screen, it worked. It’s pretty fluid on RPI3, but it takes about 30 seconds to start. Thank you very much for your contribution. ---

Looking forward to everything that comes from this! Hopefully the RD guys can get this working without the desktop. Doing that would drastically cut boot times, and that begins to take RD from a cool thing to a viable, deployable, everyday use dashboard. ---

Good stuff. I use Linux, so I didn’t realize you couldn’t access it through Windows. Since your resolution is so high, you might need to bring up your GPU memory. You’ll have to play with it to see. > [@](#): > > Hopefully the RD guys can get this working without the desktop.

Hopefully, they can, but I understand if it ends up not being worth the R&D required. Getting connections like CAN working is of higher importance IMHO. If we need faster boot times, we’ll need to upgrade to better devices, lol. ---

I wouldn’t have bought the Hat version if I knew that ahead of time. Mine is Hat, so… lol. I can’t get my Bluetooth OBD2 adapter working for some reason. It sees it and I can add it, but then no data comes across. It works on my tablet no problem 😕 Ultimately, I want to go CAN to the Pi, I just haven’t pulled up the carpet to get to my ECU yet. ---
