新的、希望更清晰的问题
这不是关于某些系统信息程序的问题
我需要知道我可以在 grub 配置中添加哪些帧缓冲模式,而无需开始计算内容并测试 1000 个命令行(因此需要 1000 次重启),据我所知 hwinfo实际上可以检测到这些模式
因此,我真正需要的是(从下面的 hwinfo --framebuffer 示例命令中剪切),如您所见,是一个模式,后跟一个分辨率,这就是该显卡支持的所有分辨率
Mode 0x033c: 1920x1440 (+1920), 8 bits
Mode 0x034d: 1920x1440 (+3840), 16 bits
Mode 0x033a: 1600x1200 (+1600), 8 bits
Mode 0x034b: 1600x1200 (+3200), 16 bits
Mode 0x035a: 1600x1200 (+6400), 24 bits
Mode 0x0307: 1280x1024 (+1280), 8 bits
Mode 0x031a: 1280x1024 (+2560), 16 bits
Mode 0x031b: 1280x1024 (+5120), 24 bits
Mode 0x0305: 1024x768 (+1024), 8 bits
Mode 0x0317: 1024x768 (+2048), 16 bits
Mode 0x0318: 1024x768 (+4096), 24 bits
Mode 0x0312: 640x480 (+2560), 24 bits
Mode 0x0314: 800x600 (+1600), 16 bits
Mode 0x0315: 800x600 (+3200), 24 bits
Mode 0x0301: 640x480 (+640), 8 bits
Mode 0x0303: 800x600 (+800), 8 bits
Mode 0x0311: 640x480 (+1280), 16 bits
然后我可以选择我喜欢的任何分辨率,将其添加到内核并确保它无需其他测试即可正常工作
后续编辑:
请在发布之前“挖掘”你自己的答案
这两个命令均未返回结果
lshw | grep -i frame
lshw | grep -i buffer
lshw 对帧缓冲区一无所知
同样地:
unset DISPLAY
hardinfo 2>&1 | grep -i frame
同样lspci
结论:似乎这里没有人真正理解我的命令实际上做了什么......令人讨厌,重新提出问题(检查顶部)
开始原始问题:
hwinfo
No command 'hwinfo' found, did you mean:
Command 'hinfo' from package 'ganeti-htools' (universe)
hwinfo: command not found
apt-get 安装 hwinfo
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package hwinfo is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'hwinfo' has no installation candidate
更确切地说,我需要以下命令的结果:(这是来自 hwinfo 仍在运行的旧系统)
hwinfo --framebuffer

答案1
Ubuntu 12.04 中的 hwinfo 已在 Ubuntu 14.04 中停用,但后来在 Ubuntu 15.10、Ubuntu 16.04 及更高版本中重新启用。在 Ubuntu 14.04 中,hwinfo 可以按如下方式安装:
下载libhd21与您的操作系统架构相匹配的 hwinfo 依赖包来自Debian 软件包:libhd21 (21.6-1)。
从以下位置下载与您的操作系统架构包相匹配的 hwinfo_21.6-1http://ftp.debian.org/debian/pool/main/h/hwinfo/
双击您下载的 libhd21 包,将其打开并在 Ubuntu 软件中心进行安装。
现在已经安装了依赖包,双击下载的 hwinfo 包,在 Ubuntu 软件中心打开它进行安装。
现在可以从终端运行 hwinfo,包括可以使用以下命令运行的 framebuffer 选项:
hwinfo --framebuffer
有关其他 hwinfo 选项的信息,请运行:man hwinfo
这些步骤在 Ubuntu 14.04 上测试过。

另一个 GUI 是hardinfo
sudo apt-get install hardinfo
答案3
hwinfo 是一个必不可少的工具。可惜 ubuntu 团队粗心地删除了它,而没有完全理解它的含义。
参照 karel 的帖子,我设法在 14.04 上安装它:
#apt-get 安装 libx86emu1 # wget http://ftp.debian.org/debian/pool/main/h/hwinfo/libhd21_21.21-2_amd64.deb # wget http://ftp.debian.org/debian/pool/main/h/hwinfo/hwinfo_21.21-2_amd64.deb # dpkg -i libhd21_21.21-2_amd64.deb # dpkg -i hwinfo_21.21-2_amd64.deb
如果您遇到依赖项错误,也许您需要从此 repo 安装 hal:https://launchpad.net/~mjblenner/+archive/ubuntu/ppa-hal
# 添加 apt 存储库 ppa:mjblenner/ppa-hal #apt-get 安装 hal hal-info

您可以使用grub 本身内的vbeinfo
或videoinfo
命令列出可用的视频模式。
