對於我的博士項目，我的導師建議安裝這個（舊的）數學軟體：http://www.gang.umass.edu/software/cmclab/index.html從需求中可以看出，該軟體運行在Linux RedHat 7.1/7.2 i686上。
我嘗試使用7.2版本設定虛擬機，安裝後作業系統以命令模式啟動，並且不會切換到桌面模式（需要使用此軟體）。我挖了一點，似乎這些舊版本無法安裝“現代”硬體的驅動程式（甚至無法識別它），因此該系統無法以圖形模式啟動，因為它不知道如何使用螢幕...
是的，據我所知，我有兩個選擇：
- 嘗試（以某種方式）在命令模式下找到並安裝適合我的顯示卡的驅動程序，並希望這可以解決問題。 [我想說極不可能]
- 嘗試安裝另一個可以運行該軟體的發行版（可能與 enigma 7.2 足夠相似）。這看起來是個不錯的主意，但我不知道我可以選擇哪個發行版。這是一個我沒有聯繫的數學家製作的軟體，所以我不能問他們是否有這樣的替代方案。
任何人都可以根據軟體網頁中提供的很少的資訊幫助我選擇「正確的」發行版嗎？或者有人對第一個選擇抱持著希望？
答案1
虛擬機器管理程式通常支援多種類型的虛擬化硬體。確保您選擇了舊的。
另一種方法是不使用本地 X 輸出：
- 您可以
ssh -X在虛擬機器中運行、執行該軟體並在另一個系統上查看 X 輸出。 - 您可以安裝應用程式可以連接到的虛擬 X 伺服器。在這種情況下，您還需要某種遠端存取（例如 VNC）。
答案2
您可以使用幀緩衝區。
程式:
Initialise X configuration files:
1. Login root console
2. Run "Xconfigurator"
2.1. At "Welcome", select Ok
2.2. At "Choose a Card", select "XGA-1 (ISA bus)"
2.3 At "Monitor Setup", select Custom
2.4. At "Custom Monitor Setup", select Ok
2.5. At "Custom Monitor Setup (continued)", select "Standard VGA, 640x480 @ 60 Hz"
2.6. At "Custom Monitor Setup (continued)", select "50-70 Hz"
2.7. At "Screen Configuration", select "Don't Probe"
2.8. At "Video Memory", select "1 mb" (or whatever the setting is in Virtual Box)
2.9. At "Clockchip Configuration", select "No Clockchip Setting (recommended)"
2.10. At "Probe for Clocks", select Skip
2.11. At "Select Video Modes", select only "8 bit: 640x480"
2.12. At "Starting X", select Skip
2.13. At "You're Done!", select Ok
Switch to X framebuffer driver:
1. Type "ln -sf /usr/X11R6/bin/XF86_FBDev /etc/X11/X"
2. Add a FBDev screen driver section to /etc/X11/XF86Config:
Section "Screen"
Driver "FBDev"
Device "Generic VGA"
Monitor "My Monitor"
SubSection "Display"
Modes "default"
EndSubSection
EndSection
Enable kernel framebuffer mode:
1. vim /boot/grub/grub.conf
2. Append "vga=773" to the kernel line (8 bit 1024×768) (for other modes see "Available VGA Modes" below) eg:
kernel /vmlinuz-2.4.7-10 ro root=/dev/hda2 vga=773
3. Reboot
Start X GUI:
1. Login root console
2. Type "startx"
X will start in the desired video mode.

如果使用 Windows，則可以使用 Xming。
先決條件：
- Virtual Box 6.0 或更低版本（因為 6.1 強制執行硬體加速，可能與 Red Hat 7.2 Enigma 不相容）
- Windows 7主機（192.168.1.97）
- Red Hat 7.2 (Enigma) 賓客 (192.168.1.109)
設定Xming：
- 下載並安裝 Xming（公共領域版本（相對於網站/捐贈者/付費版本））（您也可以從 SourceForge 取得）
- 下載並安裝 Xming-fonts
- 前往開始功能表 -> Xming -> XLaunch -> 一個視窗 -> 下一步 -> 不啟動客戶端 -> 下一步 -> 無存取控制 -> 下一步 -> 完成
設定虛擬盒：
- 建立一個新的虛擬機器 guest（例如，名稱：“Redhat 7.2”，類型：“Linux”，版本：“Linux 2.4（32 位元）”，記憶體大小：128 mb，5 GB 磁碟）
- 選擇「Redhat 7.2」虛擬機器設定 -> 網路 -> 適配器 1 -> 連接到：「橋接適配器」（與 NAT 相反）
- 按一下“確定”
設定 Red Hat 7.2 (Enigma)：
- 在 Virtual Box 上執行自訂「Everything」安裝（即 2879 mb）（勾選「跳過 X 配置」選項）
- 安裝完成後，登入root控制台
- 「ipchains -F」（清除防火牆規則）
設定膩子：
- 打開膩子
- 前往連線 -> SSH -> X11 -> 選擇“啟用 X11 轉送”
- 前往會話 -> 主機名稱（或 IP 位址） -> 192.168.1.109
- 按一下「開啟」連線到 Red Hat 7.2 伺服器
啟動圖形使用者介面：
- 在 Putty 會話中，以 root 身分登入
- 輸入“匯出DISPLAY=192.168.1.97:0”
- 輸入“gnome-session”
Gnome 將在 Xming 中啟動。
