Re: Mesa driver much slower on Stretch than on Jessie

I thought there was some talk of using Compton in raspbian? The xorg log should give the colour depth (can be found in /var/log).

Re: Mesa driver much slower on Stretch than on Jessie

On vc4 you correct monitor problems with the video= kernel command line parameter. It works like other KMS (and framebuffer) drivers.

Re: Mesa driver much slower on Stretch than on Jessie

Yeah? and topic is about Raspbian.
Jeez, this is a picky forum. I dont use raspian so I cant give a value on that.

Usually a reason for a low number is it is trying to sync to vblanc?

Has the xorg colour depth changed? That can have a big impact.

Are you now using a compositor?

ssues such as not supporting overscan compensation
Why do I keep seeing this on here? It is simply not true!

Re: Lubuntu live iso

You can do all sorts of fancy things with ISO files and embedded partition tables - http://bazaar.launchpad.net/~libburnia- ... ectors.txt

None of that is done here.

Re: Lubuntu live iso

Thanks procount you did a better job of explaining it than I did! Just a couple of things though: the link is for pi 3 only. If you want to install then use the command I gave. There is a bit of manual moving of files needed to setup the bootloader partition. I'll explain if anyone gets to that point.

Re: Lubuntu live iso

Windows 8 and 10 has native mounting of ISO files. Pretty sure mac os x had had the ability for ages. Linux certainly does. So I'm not sure what the problem is? If you are still using windows 7 or vista then just go for option b. Some of the USB flash writing tools may work too, but it depends how t...

Re: Lubuntu live iso

If it helps, think of an iso file like a zip file. It's just a convenient way of moving a number of files together. The debian installer/live build packages can work with the unextracted iso file so that is why I have used it. There is nothing complicated here. You either: a) extract the contents of...

Re: Lubuntu live iso

Unless the card is 64GB or greater, in which case the pre-format is exFAT and unusable on a Pi. I don't know anything about exFAT, but it is worth saying that of course the bootloaders have to be on a partition that is readable from a pi. Once the kernel/initramfs is loaded, then you are in the lin...

Re: Lubuntu live iso

Unless you are selling preformated SDcards the only way to put an image on an SD that i know of is to format it It's not an image. That's the whole point. You stick the iso file on any old existing partition and you boot it into a fully working system. SD cards come pre formatted, so nope you do no...

Re: Adjust screen size with OpenGL driver (vc4-kms-v3d)?

I'm not near a pi at the moment, but you can certainly adjust things with the video= kernel boot parameter. See https://ubuntu-mate.community/t/screen- ... r/11202/13 for a generic discussion.

Re: Lubuntu live iso

To answer the points raised in more detail: I ask because I've actually done some thinking about this - about how one could actually use a .ISO file on a Raspberry Pi. It is an interesting question. The usual way to boot a file is to use grub2 (https://help.ubuntu.com/community/Grub2/ISOBoot ). If a...

Re: Lubuntu live iso

I've already built it. Yes it's an ISO file. You either extract the contents to your fat formatted sd card or USB flash drive, or you boot the actual ISO file via the necessary bootloader files.

Lubuntu live iso

I'm sure somebody has done something like this before, but I couldn't find one. So I've created a lubuntu live/desktop ISO for raspi2 and 3. It means you can get a working system without having to mess around formatting cards. I find live ISOs really useful - very good when you break something! Woul...
