我按照上面網址教學安裝好driver , 不過螢幕沒有畫面出現
因為我有半年沒使用這塊顯卡不確定是不是已經故障
我目前是用主機板內建顯卡, 還是說就算顯卡沒有驅動也應該把畫面輸出到螢幕？


下面是我lspci , 我顯卡是 PCIE , 看好像沒看到有抓到顯卡

後來我把顯卡拔起來重插好像就可以偵測到但是不確定這樣就算有驅動程式嗎？

AMD Catalyst Control Center中打開後提示
初始化 Catalyst Control Center Linux 版本時出現問題。可能由以下原因引起。

未安裝 AMD 圖形驅動程序，或者 AMD 驅動程序未正常工作。
請安裝適用於 AMD 硬件的 AMD 驅動程序，或使用 aticonfig 進行配置。

lcpci 列的出來只代表說有偵測到，跟驅動程式能不能正確驅動無關

你目前 使用 什麼 版本的 Ubuntu ?

我找到原因 , 因為我啟動virtualbox 3d加速 , 需要按F8 進安全模式安裝driver 問題就可以解決

謝謝
