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?
