OPENGL 2.1 SUPERTUXKART SOFTWARE

Hence I installed lightdm per step 1 below. The better way, however, is to use an actual login DM. However, then I also needed to use 'xhost +' on the server machine to allow the clients to use the server vnc X displays.

Originally, I used VirtualGL on BionicDog64 with no login Display Manager and more recently repeated the exercise using WDL_Arch64, which by default didn't have any login DM either. VirtualGL, however, works well with Xvnc so I decided to use that (and run several vncserver instances, one for each client). However, in practice, my whole family wants individual access to the same server, so x0vncserver doesn't provide that really (well, I could run true X several times on different DISPLAYs I suppose, but seemed messy, if possible).

Note that I didn't have appropriate Xauthority permissions with this method, so on the server computer used the risky “xhost +” method to allow access to the X display from any client. Here is the command:Ĭode: Select all DISPLAY=:0 x0vncserver -rfbauth ~/.vnc/passwd

I tried the command rufwoof suggested to use x0vncserver, and it did seem to work similarly well albeit only from that one actual X DISPLAY:0 screen. As it happens tigervnc provides alternative vncserver called x0vncserver which simply sends back the already rendered DISPLAY :0 X display to the client vncviewer, which gives that solution probably similar performance to using normal Xvnc vncserver with VirtualGL. Like I said, the main desktop X (usually using DISPLAY :0) does involve direct 3D rendering. : │ ┊VirtualGL│━━━━━━━▶│ ┊VirtualGL│━━━━━━━━┛ : : :Īfter I first published about using VirtualGL, forum member rufwoof pointed out an alternative - using x0vncserver instead of the usual tiger Xvnc vncserver. Arch Linux shows diagrammatically how VirtualGL works: such that fast OpenGL games can even be played and controlled via vncviewer on the slow computer thin client. VirtualGL however intercepts the OpenGL calls and redirects them to the graphics adapter for processing there prior to returning the rendered result back to the Xvnc vncserver and the resultant speed up is enormous.

Alas, the usual Xvnc virtual X server does not use the 3D accelerated graphics available directly (so normal Xvnc rendering is 2D software slow rendering). Why? Well unfortunately software like Blender when run from main login X display (usually DISPLAY :0) uses the graphics hardware directly. However, if you simply use vnc in that manner you will find that the frame rate is hopelessly slow for using the likes of Blender (or say, Supertuxkart racer game.). Part of the actual solution is to use vnc (tigervncserver on the Folio G1 and tiger vncviewer on the 2530p). Solution is to run Blender on a server that has an OpenGL 3.3 or above capable graphics card and simply use the 2530p as a viewer.įirst thought might be that you could use the Xserver of the 2530 via say ssh -X (X forwarding), but unfortunately that doesn't work because the OpenGL 3.3+ processing instructions actually then get sent (along with X11 protocol info) back to the 2530p computer, so same issue - it cannot display the result. It is impossible to run latest Blender (and many other graphics intensive apps) on the 2530p at all. Problem is that the graphics card in that old 2530p machine is only OpenGL 2.1 capable whereas, latest Blender, for example, requires a minimum of OpenGL 3.3 to run. So I am back using old HP Elitebook 2530p (core2duo 4GB RAM machine from 2008.).

However, recently one of my family needed to almost permanently borrow the HP Elitebook Folio G1 1020 G1 with Core m vPro processor and 8GB RAM laptop I do most of my WeeDogLinux development work on. That erroneous write-up can be found here (haven't re-written it yet since still contains some useful info). no need to use vglconnect, which actually sets up an X11 connection rather than vnc). I earlier decribed the use of VirtualGL back in Dec 2020, but unfortunately some of what I did back then was totally unnecessary (e.g. Using VirtualGL with a vnc server (tigervnc) to provide fast graphics for low graphics capability client computers
