The GPU process still runs with --disable-gpu

[PhistucK]

I am starting the canary using the following flags -

"C:\Users\me\AppData\Local\Google\Chrome SxS\Application\chrome.exe" --disable-gpu --purge-memory-button --unlimited-quota-for-files --user-data-dir="c:\Personal\Temp\CleanProfileForDefaultApps" --flag-switches-begin --apps-new-install-bubble --conflicting-modules-check --enable-crxless-web-apps --enable-autologin --enable-css-regions --enable-devtools-experiments --enable-http-pipelining --enable-media-source --enable-nacl --enable-shadow-dom --enable-smooth-scrolling --enable-spdy3 --enable-style-scoped --enable-suggestions-ntp --enable-video-track --experimental-location-features --enable-experimental-extension-apis --disable-force-compositing-mode --enable-tab-groups-context-menu --flag-switches-end

I am using 23.0.1252.0 canary, on Windows Vista Home Premium SP 2 (Windows Classic theme).

But I can see still see the "GPU Process" in the Chrome task manager.

Do we care? Is this expected? Should I file an issue?

The reason for using this flag (off topic! but you can still read and comment ;)) -

I am using the --disable-gpu flag, because since Chrome 22 or Chrome 23, something has changed, I think it was related to using more of the GPU stuff and that causes my HP Pavilion dv4 to shut down its screen after a few minutes of using Chrome and never turn it on again (it seems like the system does not freeze). But I believe my computer is the one to blame, because it has serious hardware issues, like over heating and then suddenly hibernating whenever I do anything that involves too much (much is relative...) graphics like Flash, MapsGL, YouTube or even Heroes of Might and Magic III (a 1999 game), even when I cool it down using a full blown ventilator (while the air conditioner is on!)!

You can check on about:gpu to be sure, but using that command-line option means that chrome won't use your GPU, but may still use the SwiftShader software rasterizer (inside the GPU process) to render 3D.

Thank you for replying.

What exactly do I need to see there in order to be sure?

That everything is in "Software only" mode?

Also, I remember seeing more than one GPU process (with --disable-gpu) simultaneously - does that make sense?

Canvas: Software only, hardware acceleration unavailable

Compositing: Software only, hardware acceleration unavailable

Everything's in software mode, so it sounds like it's working.

We start up a second, less-sandboxed GPU process when you visit about:gpu so we can grab more information about the GPU in your system. Nothing to worry about.

Great, thank you very much for the prompt and detailed response!

You can completely disable the "GPU Process" with the following two switches:

 --disable-gpu --disable-software-rasterizer

Then the GPU Process won't start (and take up memory) at all.

Reference from: http://peter.sh/experiments/chromium-command-line-switches/

--disable-gpu ⊗

Disables GPU hardware acceleration. If software renderer is not in place, then the GPU process won't launch. ↪

I can not add this comment " --disable-gpu --disable-software-rasterizer" at the end of target libe,

I see " the target box is not valid. Make sure the path and filename are valid.

What should I do to disable GPU process????
