Switching IntelGPU NvidiaGPU on Live iso experiment

[wangjih]

Marying nvidia with linux has always triggered problems ,rants....We take the opportunity of current LiveManjaro as

the only liveiso capable of running soft switch nvidia without hassle to create exercises using uniquely live running .

and in particular a "not too complicated" switch between XorgDisplayOnIntelGPU and XorgDisplayOnNvidiaGPU with the live manjaro.

All exercises are done on Acer laptop 4GB ram with "live manjaro" using bash'ish common linux commands .

https://sourceforge.net/projects/toysbo ... x86_64.iso

we hope someone will do the same for linuxmint live iso.

updated june 16th In fact mint sylvia as well as ubuntu xenial can be switched to nvidia very easily on live iso ! Here is a very simple experiment on live Mint-18.3

Recipe

boot mint Sylvia live
in desktop's terminal:

apt install nvidia-384 nvidia-prime
ctrl-f2
in VT2 console terminal:
mint "Return" ; sudo su

systemctl stop lightdm
rmmod nouveau
modprobe bbswitch
prime-select nvivia
systemctl start nvidia

in new desktop's terminal : glxgears

On my Acer VN7 791 glxgears operates at 6000 fps fairly similar to manjaro-17.1.7 results.

while xubuntu-16.04.4 gives around 13000 fps



mint mint # apt install nvidia-384 nvidia-prime

Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
36733 frames in 5.0 seconds = 7346.327 FPS

31280 frames in 5.0 seconds = 6255.795 FPS
34836 frames in 5.0 seconds = 6967.161 FPS

Why do I get 13000fps in xubuntu on same hardware with nvidia-384 ?
The ldd results shows clearly a full use of proprietary nvidia libraries not nouveau's ones.

have fun

Hi,
I should have stressed many serious points

1 this is done on live iso -so as to always be possible to reproduce ,even volontary bugs for learning. And it does not concern only "soft switch" as in all install recipes currently in use .
Is it possible to install nvidia on live iso with the ppa method and get it running without installing of course ? If yes then it coresponds to my desire posting here : to get linuxmint-live iso with nvidia for fun.
2 compare benchmark -on same hardware of course- using optirun with respect to XorgDisplayOnNvidia results are then meaningful. see huge 3Dplot difference ! This is why the posting for triggering people curiosity
3 I would greatly appreciate someone reproduce Dr Jekyll & Mr Hyde exercise with installed linuxmint (what I showed on live iso )

Of course your work on ppa nvidia is really really useful for most of us. (with installed linux)

i miss the good old days when nvidia/amd drivers were automatically loaded in live systems. there are still a few distributions that do this but now drivers are built on boot (longer boot if you choose non-free drivers) instead of already having them included in live system already

Here is a live iso xubuntu-bionic with nvidia-390.48 and prime from MatheuGras-TimRichardson

It switched correctly on live testing with Acer VN7 laptop 4GB

Hi all
I am glad to announce a true live running latest nvidia-450.57 on linuxmint-Tricia-19.3-mate

for those who do not want to get burdens with black screen or multiple greeting login looping around but still want to play games on nvidia
or to get hands on cuda for experimenting nbody computation, deep learning .....with pure liveiso.

https://sourceforge.net/projects/toysbo ... 450.57.iso ready to use

The ax200 was includes so that thix iso could run on recent intel's wifi i.e. Acer Nitro5 gtx1650 .

The site describes recipe for nvidia's driver installation on livecd with screenshots and bechmarks

enjoy
