Dear Tim! I did some tests.
Ubuntu 14.04.2 LTS i386: $ glxinfo | grep -i vendor server glx vendor string: SGI client glx vendor string: Mesa Project and SGI OpenGL vendor string: X.Org $ lsmod | grep drm drm_kms_helper 55071 1 radeon drm 303102 5 ttm,drm_kms_helper,radeon Your command works normally scf(0); clf; plot2d(sin((0:0.01:1) * 4 * %pi)) Ubuntu 12.04.5 LTS i386: $ glxinfo | grep -i vendor server glx vendor string: SGI client glx vendor string: Mesa Project and SGI OpenGL vendor string: VMware, Inc. $ lsmod | grep drm drm_kms_helper 49282 1 radeon drm 249595 3 radeon,ttm,drm_kms_helper Your command works normally scf(0); clf; plot2d(sin((0:0.01:1) * 4 * %pi)) So I have no problems with A4-4000 APU. What exact laptop model do have? I understood about AMD A10. But may be there is a discrete (hybrid) card too?
