<\/source><\/picture><\/figure>\nWe simply contributed a bug repair to the Linux kernel \u2014 and it began with a scrolling downside on the UHK. Here is the story.<\/em><\/p>\n In 2024, scrolling on the UHK by way of modules and mouse keys already labored effectively, however then @rightaditya appeared on GitHub and submitted a pull request<\/a> to implement high-resolution scrolling on the UHK 60.<\/p>\n Excessive-resolution scrolling is a generic HID characteristic developed by Microsoft, then ported to the Linux kernel. I did not learn about this characteristic. @benedekkupper, our USB\/Bluetooth skilled, ported<\/a> this characteristic to the UHK 80, bringing high-resolution scrolling to all UHK fashions.<\/p>\n After utilizing high-res scrolling, it turned instantly apparent how jarring strange scrolling felt by comparability. I exploit the trackpoint module all day, and scrolling turned buttery clean and a pleasure to make use of. As a desktop person, it makes an enormous distinction when scrolling by way of internet pages within the browser or supply recordsdata in an editor.<\/p>\n However then I seen<\/a> that scrolling was extraordinarily gradual after I suspended and resumed my PC. At first, it appeared like a typical firmware bug till Benedek not solely realized it was a Linux kernel bug but in addition submitted a kernel bug repair<\/a>. Benedek seen that though we had simply hit this bug, others have been dwelling with it for 7 years<\/a>!<\/p>\n We did not count on the repair to be merged anytime quickly, assuming a sizeable backlog, however to our shock, it was merged<\/a>, and is now a part of kernel 6.19!<\/p>\n
