使用 AMD 卡移动屏幕两个驱动程序

运行 OS 12.3 时，我在使用 AMD HD 7670M 和 FGLRX 和/或 radeon 驱动程序时遇到了屏幕参差不齐和/或移动的问题。

完整帐户可在此处找到： SuSE硬件论坛

简而言之：无论我做什么 - 屏幕要么向右移动并包裹（从显示器的 1/4 到 3/4 不等），要么出现奇怪的移动条纹（重新启动时宽度会有所不同）。

唯一有效的是故障安全模式。

任何帮助将非常感激！这是我运行 get-edid 时得到的结果：

./get-edid: get-edid version 2.0.0

Performing real mode VBE call
Interrupt 0x10 ax=0x4f00 bx=0x0 cx=0x0

The EDID data should not be trusted as the VBE call failed

这是 parse-edid 强制转换的输出：

./parse-edid: parse-edid version 2.0.0
./parse-edid: EDID checksum failed - data is corrupt. Continuing anyway.
./parse-edid: first bytes don't match EDID version 1 header
./parse-edid: do not trust output (if any).
