Solution: Build a kernel for HP Omni 120 based on Linux kernel 6.4.13 Step 1: Download Linux kernel 6.4.13 and extract: "wget https://cdn.kernel.org/pub/linux/kernel/v6.x/linux-6.4.13.tar.xz"; "tar xvf linux-6.4.13.tar.xz"
Step 2: Install additional packages for building a kernel "sudo apt-get install git fakeroot build-essential ncurses-dev xz-utils libssl-dev bc flex libelf-dev bison" Step 3: Configure Kernel Navigate to the linux-6.4.13 : "cd inux-6.4.13" Copy the existing Linux config file: "cp -v /boot/config-$(uname -r) .config" Make a default configuration file: "make menuconfig" -> Save -> Exit Step 4: Edit drivers/gpu/drm/drm_edid.c in folder linux-6.4.13 (Visit https://gitlab.freedesktop.org/nouvelles/kernel/-/commit/2682768bde745b10ae126a322cdcaf532cf88851 for more details) Remove /* Some EDIDs have bogus h/vtotal values */ if (mode->hsync_end > mode->htotal) mode->htotal = mode->hsync_end + 1; if (mode->vsync_end > mode->vtotal) mode->vtotal = mode->vsync_end + 1; Add /* Some EDIDs have bogus h/vsync_end values */ if (mode->hsync_end > mode->htotal) { drm_dbg_kms(dev, "[CONNECTOR:%d:%s] reducing hsync_end %d->%d\n", connector->base.id, connector->name, mode->hsync_end, mode->htotal); mode->hsync_end = mode->htotal; } if (mode->vsync_end > mode->vtotal) { drm_dbg_kms(dev, "[CONNECTOR:%d:%s] reducing vsync_end %d->%d\n", connector->base.id, connector->name, mode->vsync_end, mode->vtotal); mode->vsync_end = mode->vtotal; } Step 5: Start building the kernel. Note: It may take hours to complete. "scripts/config --disable SYSTEM_TRUSTED_KEYS" "scripts/config --disable SYSTEM_REVOCATION_KEYS" "sudo make -j$(nproc)" Press Enter 2 times to confirm the default options for the generation of new certificates. Step 6: Install the compiled kernel "sudo make modules_install" then "sudo make install" Reboot and the flickering disappear. This issue has been existing for over a decade, so I hope anyone suffering from this issue can now fix it. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-5.11 in Ubuntu. https://bugs.launchpad.net/bugs/1964916 Title: [HP Omni 120-2110il AIO] Flickering white lines on screen Status in linux-hwe-5.11 package in Ubuntu: Confirmed Bug description: https://www.youtube.com/watch?v=GcAXAicoZqY this is the video of my error i am having this issue on all versions of ubuntu-- i have tried installing versions 20.04, 18.04.06, 12.04.. i have intel pentium g630 processor with intel graphics 2000 (Vram-256M).
