      I have an Touch screen, where drivers is available only in .img packages. (so I cannot use the RetroPie IMG and manually install drivers). The upgrading the things updates the some drivers and broke display drivers. Is possible to disable the auto upgrading in RetroPie-Setup?

        There is no auto upgrading, but if choosing a full binary install it does do a sudo apt-get update; sudo apt-get dist-upgrade - You can "hold" the packages you don't want upgraded though. So if it was the firmware/kernel you need to not upgrade you could do

        echo "raspberrypi-bootloader hold" | sudo dpkg --set-selections

          I would add that if the vendor is providing this custom Raspbian image with drivers that has for example a custom kernel, then they should have already either done this, or provided another method to avoid losing their changes.

            Nice, thanks! This helped, I installed all things, but when I ran EmulationStation (and of course turned off the LightDM), cursor is still only blinking on top right corner. Any ideas?

            I have KeDei 3.5 inch display

              That is one problematic display, there's like 5 different versions all with their proprietary images. You should contact your seller for help, they should know better. I don't mean to sound like we're not trying to help but really if you do a search for kedei you're gonna find nothing but frustration.

                I found a drivers here:
                (http://en.kedei.net/raspberry/v5/LCD_show_v5.tar.gz)

                BTW, That display have low refresh frequency, its possible to make it faster?

                Thanks!

                  As far as I can tell, nope. Controller driver is some clone ILI9341. According to notro it writes 8 bytes per 16-bit word, display has in effect a combined 16-bit databus and an 8-bit control bus rolled into one 24-bit serial bus so bandwith is really throttled.

                  Honestly, even if you get it to work it will not be usable for Retropie at all. Sorry.

                      Okay, thanks for replies. So, can you give me a tip for cheap 3.5 inch display from Aliexpress or ebay what will handle this?

                      Thanks :-)

                        @GAMELASTER if you want something reliable aliexpress or eBay are bad choices and you'll run into the same issues as above. Find reputable pi supply places like adafruit or pimoroni or pisupply

                          If you're looking at GPIO tft screens, I'd not recommend 3.5" (or 4") as those are likely 480x320, too many pixels to push for acceptable framerates, you'd also be getting a lot of tearing and stuff.

                          Largest size I have good experience with would be 3.2" so just search for those or smaller. AFAIK from 3.2", 2.8", 2.4" to 2.2" most are 320x240 and use the same controller chip, meaning there would be an overlay for them so should work quite well with Retropie. Some come with touch input but I've never messed with those.

                          If you want larger screens, but no touch input, you can try those cheap car backup screens, sized from 3.5" to 4.3" or more. They are VGA so it's easy to set up, no drivers needed. You'd need to get a 3.5" AV breakout cable and splice that or make your own. And of course with analog they're not going to be the best looking /sharp, but fast and quite acceptable. A lot of people use them in "gameboy" type portable setups.

                          If you want sharp and large screens, with or without touch, then choose from the 5", 7" or larger HDMI ones. You'd need to set up your config.txt depending on which models, but generally this would be the easiest, just (almost) plug and play.

                            Thanks for the tips! I want to make the portable console, so I need an small display (to thickness too).
                            First time I bought the car backup TFT display, but its not delivered, so I refunded and bought this with though it will be better.

                            To Adafruit things, Im from Slovakia where as student I cant buy things like Adafruit PiTFT, this display from Ali is for me alot expansive, so the PiTFT is insta killer.

                            Thanks guys for tips, I will try to found something useful :-)
