Comment 36 for bug 1272291

nwm. Solved.
I used the beta driver cause i had problems installing the stable one.

Install 13.12 from amd site.

amd-catalyst-13.12-linux-x86.x86_64.run --extract catalyst
Remove everything from this part to the end of the file within catalyst/common/lib/modules/fglrx/build_mod/kcl_acpi.c
FROM:
----------
#if LINUX_VERSION_CODE >= KERNEL_VERSION(3,6,3)
    if (!ACPI_SUCCESS(acpi_get_table_with_size(id, 0, &hdr, &tbl_size)))
#else
    tbl_size = 0x7fffffff;
    if (!ACPI_SUCCESS(acpi_get_table(id, 0, &hdr)))

sudo ./ati-installer.sh 13.251 --buildpkg Ubuntu/saucy

No more mouse glitches.
Have a nice one.
