multiple cards and monitors with xrandr and opengl
Hi, Thanks for your advice..! I have a few follow-up questions (tagged below Q1, Q2 and Q3). Any help highly/extremely appreciated. Regarding to "reverse prime", etc. I have read the following page: https://nouveau.freedesktop.org/wiki/Optimus/ So, if we want a single "macro" xscreen that spans two cards, for example: Card 0, connected to monitor 0 Card 1, connected to

OpenGL context switching with Noveau
Dear Devs, (I hope this question is not that much OT for this list..) My question is about fast OpenGL context switching, i.e. when there are several processes using the same nvidia card, each one with their own OpenGL context. In my specific case, I am trying to dump 720p video simultaneously to multiple windows using OpenGL textures. So, to begin with, I have a process that spans child

OpenGL context switching with Noveau
For details see my presentation on day 3 of XDC2016. TL;DW: A context switch on average takes ~25 microseconds, but depending on the display resolution and the load on the card times up to 130 microseconds have been observed. The average does not appear to differ much between cards as the (growing) size of the context is in balance with the increased DRAM bandwidth. Measured worst cases

OpenGL context switching with Noveau
Context switching = very slow on NVIDIA. Don't do it if you can avoid it. Each context is like a megabyte of data, if not more. Each time it has to get saved off and restored.

Nouveau and multi-monitor setup for Quadro NVS450 (G98)
Hi, I have a NVidia Quadro NVS450 graphics card with on screen (4800 x 1200 pixels) over three monitors. I use the proprietary NVidia modules to achieve accelerated 2D graphics and display effects. Since about the beginning of 2014, probably related to changes in the X11 or compositing manager, I experience screen lockups lasting from few seconds to several minutes. I therefore would like to

regression? no more separate xscreens
Dear Devs, The support for multiple xscreens (i.e. no xinerama, just separate :0.0 and :0.1 displays) in nouveau is broken. It would be great if someone could confirm this. It is easily done, by commenting the "xinerama" option from the xorg.conf file: https://nouveau.freedesktop.org/wiki/MultiMonitorDesktop/ With the nvidia proprietary drivers separate xscreens work fine.

[LLVMdev] Generating machine code directly to memory

What I would like to do is something like this: Compiler: Scripting language (Antlr) -> LLVM IR -> (Optimization) -> Raw Machine code -> (Transport media) -> Execution The idea is that I could compile my scripts directly to asm without any extra steps and in

Cannot start a secondary Xserver with resolution 6480x3840
Hi, In my workflow I am using several separate xservers. One for work, another for research and so on. Each of them has a separate user account, and they all belong to the same (main) group called janek. I've been using nvidia for years, but about 2 years ago some super annoying bug appeared in nvidia, namely that switching between virtual terminals sporadically causes nvidia_modeset to

4 monitors with one graphics card and standard driver
I've just test an ATI FirePro 2460 graphics card on CentOS 6.4. It connects 4 monitors. It worked with the standard radeon driver. I was able to arrange the monitors into my preferred configuration (as a square array, 1 upper left, 2 lower left, 3 lower right, 4 upper right) simply by clicking System -> Preferences -> Display, and then moving the four monitor images. This creates the

Feature request: Multi-head awareness in compiz and plugins
There have been offered several patches in order to forward Xinerama support to Xgl and patches for compiz to make use of it (like iXce's ones, which were ignored). So far the patched up compiz is working pretty good and makes it effectively usable in such setups (aside of that those patches will always drift away from official CVS and need to be touched for each commit). However it seems

This results in wrongly proportioned plots, wrongly positioned text etc. Other devices are not affected. I already asked
