前段时间整了个显示器，Windows, grub 时是正常的，但进 Linux 后就无法使用了。
问题描述
环境：Debian 12
xrandr 会显示
按照 Google 上的一些结果，进行了重装显卡驱动等操作，都不太行得通。
还发现 Debian 11 可以输出 HDMI 的，然而这个版本无法调节亮度。
更多信息
后来，想起 taoky 的博客里有一篇提到因为 i915 无法使用 HDMI 的问题：调试一则：让 i915 在 ThinkPad T14 Gen3 上正常工作
尝试关闭 i915 内核模块，发现和 Debian 11 一样可以输出 HDMI 但不能调亮度。可以肯定是 i915 的问题。
然后按照博客，编译安装最新版本的内核 6.1.0-rc5+，新版内核还没有修复这个问题。
查看开机后的 sudo dmesg 发现问题不同，我的里有 3 个 cut here

解决方案
找到了 No HDMI signal i915 0000:00:02.0: [drm] ERROR crtc 131: Can’t calculate constants, dotclock = 0!。
按照其中的 patch 文件更改 drivers/gpu/drm/i915/display/intel_ddi.c 文件中的 intel_ddi_init 函数。

encoder = &dig_port->base;
encoder->devdata = devdata;
+ if (port_name(port) == 'B') {

+ init_hdmi = 1;
+ }

if (DISPLAY_VER(dev_priv) >= 13 && port >= PORT_D_XELPD) {
drm_encoder_init(&dev_priv->drm, &encoder->base, &intel_ddi_funcs,
DRM_MODE_ENCODER_TMDS,

似乎是 BIOS 对 VBT 初始化的问题
然后重新编译内核。

cp /boot/config-$(uname -r) .config
make oldconfig
make localmodconfig
make -j $(nproc)
|
安装并更新 grub。

|
sudo make modules_install
sudo make install
sudo update-initramfs -u -k all
sudo update-grub
|
这样可以暂时性地解决问题。只是，内核有些东西不太能用，比如显卡驱动、docker（也可能是我编译选项设置得有问题）。
2023-12-5 更新：仅替换 i915 内核模块
下载 apt 打包时的源码：
1
|
apt source linux-image-6.1.0-13-amd64-unsigned
|
在 drivers/gpu/drm/i915/display/intel_ddi.c 中找到 intel_ddi_init 函数，修改此文件。
commit 完。打包编译，大概需要编译一个小时
1
2
|
dpkg-source --commit
dpkg-buildpackage -us -uc
|
然后提取其中的 i915.ko，替换掉 /lib/modules/$(uname -r)/kernel/drivers/gpu/drm/i915/i915.ko。
更新 initramfs：
1
|
sudo update-initramfs -u -k all
|
这样就可以只替换 i915 内核模块，解决 HDMI 输出的问题了。
