My statement in the bug description claiming "The 32 bit version works fine under the same 64 bit system." just means the rendering is working without freezing the system, not that you have an usable Webots Rejecting the Lucid task this has an easy work-around (using the 32bit version), and we don't seem likely to have a fix in time.Į.g. The invalid memory reference seems to be a bug of Webots, but unfortunally this means it is not usable under Lucid for more complex tasks than a very simple demo behavior without any camera.

Unfortunately this is not true for my special case, since the 32 bit versions has other problems.Į.g. ?

But in #298532 the reporter explicitly mentions that both 32 bit and 64 bit versions will crash. net/ubuntu/ +source/ xserver- xorg-video- intel/+ bug/298532. Webots might use reflection in their rendering internally (I have contacted the vendor about that) and this bug might be related to https:/ /bugs.launchpad. Try adjusting the vblank_mode configuration parameter. This is the last message from the command line (subscribed to a good old sheet of paper):ĭo_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly. The 32 bit version works fine under the same 64 bit system. ![]() Since then the 64 bit version of Webots will freeze the system (even Alt+Print+K won't restart the X server, I need to poweroff the machine manually). The commercial robot simulator Webots (free demo version at webots/ download_ linux.html) recently switched to Ogre for their rendering engine. Binary package hint: xserver- xorg-video- intel
