Re: free some RAM

Have you installed the downloaded ".deb" file?
Like:

Code: Select all

dpkg --install zram-config_0.5_all.deb
Maybe a re-boot is neccessary afterwards.

Re: free some RAM

My linked Wikipedia page writes: When used for swap, zram … allows Linux to make more efficient use of RAM, since the operating system can then hold more pages of memory in the compressed swap than if the same amount of RAM had been used as application memory or disk cache. This is particularly effe...

Re: free some RAM

zram usually helps, too, in particular for machines with not-so-much RAM. If I remember right, it's been part of previous versions of Raspbian, and it's still in Debian-based Ubuntu, so depending on which Raspbian version you use, you could activate it via: sudo apt install zram-config To see what ...

Re: Good reasons to buy the latest Rpi 4 with 4G RAM?

The RPi has a built-in troll detector. If it detects a troll it starts doing strange things. Clearly the Pi has one of the best built-in troll-detectors available. Back on topic: A Pi4 with 4 GB RAM is a great desktop machine. With enough RAM, Linux buffers IO (input/output) data and files so effic...

MAME (+MESS) runs great on Pi4

For the MAME friends out there, I'm happy to report that on the Pi4 several tested systems now run 100% in full-screen. This is with mame version v0.206 directly from Raspbian's apt package. Also some emulated home computers run 100% now in Mame, for example Amstrad CPC and Megadrive. So finally we ...

Looking at reviews online many people have reported thermal throttling even with a heatink installed. Is this an issue with software or limitation of heat dissapation?

Are you using the legacy driver or one of the KMS drivers? buster default FKMS. Omxplayer won't run on Raspbian 10-Buster when you use the fkms or kms driver, i.e. when your /boot/config.txt file has in it this line: dtoverlay=vc4-fkms-v3d or dtoverlay=vc4-kms-v3d Remove it and omxplayer works agai...

Mednafen runs a lot better complied from source. Why is this? Do you happen to know if a source compiled Mednafen on a Pi3 runs the SNES emulation with 50 fps, like it does with the Megadrive emulation? Because from Raspbian's repository and run on a Pi3, Mednafen gives 50fps for Megadrive emulatio...

Since from Raspban's apt-repository, the many-machine-emulator MAME+MESS¹ works reasonalbe well on a Pi3 for many selected titles, and for more optimised emulation of popular consoles the Mednafen² emulator works even better, these two should also run extremely well on a Pi4 out of the Raspbian box....

Re: Raspberry Pi 4 Thread - general discussion

Can we get any more information on the expected computational capabilities and performance difference of the VC6 GPU compared to the VC4? It's about 4x faster than the VC4 (pixel rate IIRC).

Re: Why is the RPi4 being advertised as a desktop computer?

I suppose I could be described as a 'power' user, in that I write software, build kernels etc. That, some would say, requires a decent desktop computer. And yet EVERYTHING I do nowadays can be done on a Pi4. [..] So, even though this is a tiny ARM based device, I would have no problems doing my act...

Thanks for your reply. Please note that local users even without admin-rights can on my Pi use "sane-find-scanner" and the GUI application "simple-scan", i.e. everything needed.

Re: New graphics driver: does it work on older Pi's?

It works on the Pi3, but is visibly slower with Raspbian Buster than it used to be with Raspbian Stretch, when it comes to OpenGL applications like Hatari, MAME, etc. For example on Hatari it's a 20% slow-down, meaning compared to Stretch there's now frame skips and the emulated sound isn't in sync ...
