Xlib: extension "GLX" missing on display ":0". How to enable WebGL in Ubuntu? xorg?

Question

linux

I decided to run WebGL on my Ubuntu 14.04 in Google Chrome. It didn't work..
First I determined that my card is from nvidia:

$ sudo lshw -C display
  *-display               
       описание: VGA compatible controller
       продукт: G94 [GeForce 9600 GT]
       производитель: NVIDIA Corporation
       физический ID: 0
       сведения о шине: [email protected]:02:00.0
       версия: a1
       разрядность: 64 bits
       частота: 33MHz
       возможности: pm msi pciexpress vga_controller bus_master cap_list rom
       кофигурация: driver=nvidia latency=0
       ресурсы: IRQ:42 память:fa000000-faffffff память:e0000000-efffffff память:f8000000-f9ffffff ioport:9000(размер=128) память:fb000000-fb07ffff

I installed the proprietary driver nvidia-311 driver, as a result, the x system did not start:

[ 19431.654] (WW) Warning, couldn't open module nvidia
[ 19431.654] (II) UnloadModule: "nvidia"
[ 19431.654] (II) Unloading nvidia
[ 19431.654] (EE) Failed to load module "nvidia" (module does not exist, 0)

After a little digging, I determined that my card was not powered in the right way
For everything to go, only the NoPowerConnectorCheck option was missing, it started:

[   101.709] (==) Matched nvidia as autoconfigured driver 0

And now I already want to run WebGL in Google Chrome, and there is no GLX:

$ glxinfo
name of display: :0
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".

Xlib:  extension "GLX" missing on display ":0".

Again I look in /var/log/Xorg:

How so? How to enable WebGL in Ubuntu 14.04 on Google Chrome? xorg?

Answer 1

What video card, what drivers?
In advanced settings -> Use hardware acceleration when available
chrome://flags/ -> Override software rendering list -> Enable (it's better to see what kind of video card first)
