Hello. I I have been a resident in SL since 2015. This is my first post in this forum because I have been rendered desperate for answers in regards
to why my computer shuts down completely and randomly when I am in-game using any viewer and irregardless of the graphics settings in Ubuntu 18.04 64 bit linux. I am a Ubuntu user with a 2013 Acer V5 series laptop with Intel HD 4000 Graphics(and thus uses mesa drivers for OpenGL rendering and intel i915 as my graphics driver) onboard as its integrated graphics adapter. Now hear me out. When this laptop was brand new, I never had these problems using any of the viewers as long as I set it to low settings the worst thing it would do is close the program and not crash the entire system. But as the viewers updated and with drivers and OS versions following the same route, I noticed an increasing demand on
the system to the point where I had to use lightweight viewers like Cool VL Viewer in order to be stable. For a while Cool VL viewer seemed to work without any problems, I could travel anywhere,be in any crowd or in a quiet sim without crashing albeit i did had some random crashes that werent fatal and infrequent from time to time but as long as it was set to low settings and object/mesh details were low/mid,everything worked as it should. This was on Ubuntu 16.04 which i had upgraded from not too long ago. I updated my system from Ubuntu 16.04 to Ubuntu 18.04 64-bit and this is where the trouble starts. Now it randomly crashes no matter what I do/where I am after a couple seconds even in Cool VL Viewer. I noticed that when im in certain areas of a sim or if i pan my camera to a certain spot(this used to happen when my camera is rendering potted plants or trees in Firestorm and is a consistent problem with other viewers as well) the likelihood to fatally crash and shutdown is almost 100%. I had found out that a kernel version seemed to help with the problem a bit but then it eventually started crashing even on the older kernel(4.4.137). Also note that i can use other programs that can be equally demanding and they do not crash the system. I have cleaned out the laptop and applied thermal paste to the CPU 4 months ago and I can feel cool air blowing out of the vents so I do not believe this is an overheating issue although it could be. Another notable issue is that the CPU fan is constantly high,even when the system is idle and it started behaving like this when i first cleaned it. Is it truly time to throw in the towel and buy a new laptop or is this a glitch/graphical that i can fix?
