You'll currently see something like this if you attempt to connect to a VNC Server running on a device which doesn't have enough GPU memory:\n\n![image](https://cloud.githubusercontent.com/assets/2833067/14882690/cf5a0776-0d31-11e6-98f0-fbe216fd5fee.png)\n\nIf this happens, please try setting your GPU memory to 128MB via raspi-config, and try again.\n\nSimilarly, if you _are_ able to connect via VNC, but you find that applications requiring the GPU aren't working (e.g. Minecraft), then you may also need to increase your GPU memory.\n"},"comment":{"url":"https://api.github.com/repos/RealVNC/raspi-preview/issues/comments/260734218","html_url":"https://github.com/RealVNC/raspi-preview/issues/3#issuecomment-260734218","issue_url":"https://api.github.com/repos/RealVNC/raspi-preview/issues/3","id":260734218,"user":{"login":"Ruffio","id":1877612,"avatar_url":"https://avatars.githubusercontent.com/u/1877612?v=3","gravatar_id":"","url":"https://api.github.com/users/Ruffio","html_url":"https://github.com/Ruffio","followers_url":"https://api.github.com/users/Ruffio/followers","following_url":"https://api.github.com/users/Ruffio/following{/other_user}","gists_url":"https://api.github.com/users/Ruffio/gists{/gist_id}","starred_url":"https://api.github.com/users/Ruffio/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Ruffio/subscriptions","organizations_url":"https://api.github.com/users/Ruffio/orgs","repos_url":"https://api.github.com/users/Ruffio/repos","events_url":"https://api.github.com/users/Ruffio/events{/privacy}","received_events_url":"https://api.github.com/users/Ruffio/received_events","type":"User","site_admin":false},"created_at":"2016-11-15T19:02:33Z","updated_at":"2016-11-15T19:02:33Z","body":"Has this issue been resolved or should it be closed?"}}
