I seem to have developped some problems with mathematica on one of my boxes; there is potentially an xorg issue. The graphics card is an [AMD/ATI] RV730 XT [Radeon HD 4670].
The issue cropped up recently: If I type \[UpArrow] and hit return, the uparrow is not displayed in the output (it is in the input). Changing the format of the output cell (Tried every option) doesn't affect this; copying and pasting to an input cell and it is displayed again. The version of Mathematica is 9.01 on 64-bit Scientific Linux 6.5 and it seems likely that this happened on updating SL from 6.4->6.5; there are now issues with 3D graphics as well (I now need to do "mathematica -mesa" to show 3-D graphics) Opening notebooks that were created on my work computer generates a huge number of failed assertions, all of which seem to be linked to missing glyphs. I am trying to chase this up with wolfram, but have the feeling this may be a graphics issue: Anyone seen anything like this before? Niels --- Prof. Niels R.
