Ah and you run Graal on it? It's 5-6 years since the last 32 bit Intel/AMD CPUs were produced
Well anyway:
A new version for Linux (64 bit) has been uploaded: v6.037
It brings a lot of new stuff since the last v6 release and of course plenty of new things compared to v5. Download it as usual from the website although the download from login server should work if you have installed it as user:
http://www.graalonline.com/downloads/Graal6_linux64.zip
This new version is not scanning the current folder anymore, so it should be much easier to just put it anywhere and then run it. Unzip the file, make it executable, then run it:
unzip Graal6_linux64.zip
chmod 775 Graal
./Graal
All files will be download and saved to ~/.graal/graal4 in case you want to clear them or need to find the screenshots or recorded videos. The new version is using "SDL mixer" for playing sounds and music. Depending on the hardware and drivers this should work pretty well, but if there are problems then just disable sounds or music in the options on the login server.
