首先，我先聲明一下，我對 MATLAB 和 Linux 還很陌生，也許我遺漏了一些明顯的東西，如果是這樣，請耐心等待。
我被要求幫助我的數學系的一個建模項目，所以我下載了所有程式碼，在我的電腦上安裝了 matlab，並在經歷了一些麻煩之後（必須安裝一個名為“glu”的庫）腳本本身實際上運行。我相信它正在嘗試渲染一個使系統崩潰的圖，我無法使用 ctrl-alt-F（任何東西）訪問其他 tty，過了一會兒我在右上角看到一個閃爍的遊標，仍然無法執行任何操作，ctrl -alt-delete，什麼也沒有。所以我按住電源按鈕並關閉電腦。
我找到了故障轉儲，其中很多都是空的，有些確實有一些訊息，這裡是「matlab_crash_dump.4121-1」：

此時我很確定這是一個圖形問題，我也嘗試過opengl軟體渲染。這個專案的主管建議核心可能有問題，因為它正在破壞我的整個系統，此時他希望我切換到不同的環境，以便我們可以繼續前進，儘管我仍然想知道gentoo 到底怎麼了？
我在想的一件事是我沒有 DE，只有平鋪 WM（很棒的 3.5），我不知道這是否會導致問題，只是一個想法
這是我正在處理的內容：
Matlab2016a
太棒了 3.5
gentoo-4.4.6
英特爾2760M
Quadro 2000M（我認為它沒有使用這個）
20GB內存
以及這些部件的標準驅動程式
如果您還有其他需要，請告訴我。
